Angular JS vs. React –Which Is The Right Course For You In 2023?

Choosing a career can be quite overwhelming for many students. To find the perfect field, students must evaluate themselves first and stay determined in whatever they choose. In the 21st century, everything revolves around technology. Modern life is incomplete without it. If you love and enjoy technology and particularly keep up with the latest updates in the IT field, this is the right time to be a part of it. You may have several options around you, but hear us out when we talk about the React JS or Angular course. It can be quite beneficial for you.


In recent years, the variety of framework alternatives has rapidly grown, and exciting new opportunities are always emerging. But as of 2019, Angular and React have maintained their dominance. These programmes have undergone a significant evolution. JavaScript is frequently used for front-end development since it is a well-liked language with extensive capabilities. The utilization of JavaScript technologies is expanding these days, making it challenging to select the best technology stack to develop mobile apps one at a time.


Front-end web designers and developers have a lot of choices and decisions to make. They have to choose what programming language, what sort of tools, and what CSS framework to utilise. However, none of these choices has a greater influence than choosing a UI framework.

You, as students who need to decide on your career goal, should assess carefully. React JS course vs. Angular course – which is the best? Selecting between these two can be quite confusing for many who are looking for a skyrocketing career.


In 2023, what will be a better option for web development? Is the Angular course preferable to React JS? Or is React superior to Angular? Let’s compare the two modern emerging technologies, React JS and Angular JS to know which course is suitable for you.


What is Angular?

Before choosing the best Angular course after graduation, know what Angular is. Angular is an open-source frontend web app framework. By using HTML, CSS, and Typescript, developers can create scalable, high-performing, and robust single-page apps using Angular. Model View Controller is the framework’s preferred organizational system. A structure like this makes it possible to divide some jobs into logical pieces, which reduces the time it takes for a web page to load. An added advantage of the MVC approach is- the separation of concerns, which lets angular developers keep the view component on the client’s side and reduce background requests.


The technology offers a wide range of pre-made solutions and a well-designed framework for gathering and storing data. This makes building massive websites easier and guarantees their dependable functioning. Did you know that the Google Angular Team makes contributions to the updated version of Angular’s advanced development? This makes it quite a preferred framework for many.


What Can Angular Do That React Can’t?

If you remain bewildered with which option to choose from- the Angular course or React JS course, know about what Angular can do that React can’t. It may give you an idea about Angular from a different perspective-


  • Full-fledged framework

Angular is a complete framework with several features to develop software. As a result, it lets people solve various tasks by utilizing ready-made modules. This is not the case with React, whose functions are restricted to working just with the user interface elements. If you work with Angular, there are UI-router (a module for routing), NG-table (working with tables), and UI- grid.

  • Bidirectional data binding

A phenomenal feature like bidirectional data has changed the game in technology. It lets the user recognize elements at the “View” layer and modify them synchronously when the data changes “Model” components. Wondering how that works? At the Model layer, Angular keeps track of user activities and modifications to child components, updating the required interface templates. The tools or technology doesn’t need to alter low-level structures to do these manipulations; instead, all modifications are made by prescribing them in the Model layer.

  • MVC pattern

The MVC pattern is the foundation of Angular. As a result, the Model, View, and Controller levels of the data flow for an Angular project are interdependent.

  • Framework features

Dependency injection and component-based routing are components of the Angular framework. Unlike React, you do not require extra tools to implement them.


What is React?

Just like you know about Angular, it’s time to know about React a bit. So what is React? React was developed by Facebook (now Meta) to create a user interface. React JS, an open-source Javascript framework offers a comprehensive bundle of component-based workflow and lean architecture. For front-end development, it uses technical language.

To enhance high rendering performance, Facebook built this product. One major benefit that has attracted a sizable, enthusiastic, and extremely active community to ReactJS is that it is open-source. React is used in industries like entertainment, retail financial technology, media and artificial intelligence. It is quite popular among developers all over the world. But don’t yet jump to conclusions about the best React JS course after graduation. We still have a few points to cover.


What Can React Do That Angular Can’t?

We have already discussed what Angular can do that React cannot. In this section, you’ll learn about what React can do that Angular can’t. Let us dive into it-


The primary feature of React is that it has virtual DOM implementation. This is different from Angular. It uses only real DOM. This refers to the document object model letting users have access to and modify its layout, content and structure.

Are you wondering how it all works? The Document Object Model or DOM is an object that holds data about the state of the interface. It enables users to view and modify the content, architecture, and appearance of HTML documents. However, efforts to change HTML components gave rise to the idea of virtual DOM.

These are some features of React-

  • JSX advantage
  • Isomorphic javascript
  • Single data binding
  • Building blocks flexibility


Angular and React- A Brief History 

When you have to think about Angular or React JS course as your career, you should know the history of the field to understand the changes, the cause of its change and how it grew or collapsed. In this section, we will briefly let you know about the history of both Angular and React JS.


Angular History

A web framework created by Google called Angular was first made available in 2010 as a tool to help create business apps. Miko Hevery, a Google developer, and Adam Abrons, a teammate, built the framework. The idea for the project’s name came from Abrons. The project was given the name Angular because it was designed as an addition to HTML. This addition uses the syntax known as angle brackets. It quickly rose to prominence as one of the leading web frameworks of the time.


The service could be found at because the domain was already taken. However, the creators of Angular soon gave up on the notion of creating software and chose to make AngularJS available as an open-source framework.


In 2014, an announcement was made about Angular JS 2.0. It was written entirely in TypeScript. In contrast to its predecessor, AngularJS 2.0 was created as a brand-new framework. The previous version, known as AngularJS, continued to develop separately till 2022 when Google refused to support it. The present version, called Angular, was released on September 15, 2016. Up until June 2022, the latest version of Angular has been Angular 14.1.0.


React History

Coming to React technology, was developed by the developer of Facebook, Jordan Valke. The system Valke developed was initially incorporated into the Facebook feed in 2011, and the Instagram app in 2012.


React was once marketed as a closed tool that was only meant to be used by Facebook developers. However, at the 2013 JSConf US convention, the technology’s source code became fully open. In February 2015, at the React-focused Facebook convention, the launch of a new platform called React Native took place. It enabled React to be used as a mobile app. React Native’s source code became available a month later.


Facebook later unveiled React Fiber, an enhanced and optimised version of React, in the spring of 2017. In June 2022, the company released the latest version- React 18.2.0.


React vs. Angular: Popularity Growth

When you consider getting admission for Angular or React JS training in Kolkata, you have to keep in mind the current demand and popularity. Both have gained so much popularity and name. We all know how it’s important to have a high-performing and functional app in today’s date. That’s exactly what Angular and React give the majority of the population. In this section, you’ll know the key factors that have made these successful tools. You will have a better understanding of how Angular JS and React compete for popularity.


  • React vs. Angular: Google Trends

According to Google Trends, both React and Angular have been at par with one another till 2020. The interests in both remain favourable. After 2020, there was a significant gap. In this phase, React overtook Angular by a definite margin. It has remained so till July 2022. However, you should know that this is not an appropriate scale. Why? Because Angular has a slimmer audience pool, that is an enterprise application. On the other hand, React is used in almost every place, therefore, it is obvious that React will cover a larger market space.


  • React vs Angular: Stack Overflow Trends

According to Stack Overflow Trends, React JS has 381,948 questions tagged and 275,940 questions tagged. You might wonder what it signifies. These numbers mean that people are more curious about React than Angular. The vast community and groups dedicated to each—Angular and React, signifies that people are far more inclined towards React. The numbers also show that people have a wider and faster support system for React rather than Angular. Stack Overflow is an ideal popularity benchmark if you want a developers’ perspective. You may argue that having more questions tagged doesn’t mean it has wider popularity, but it does provide a sense of curiosity and active community.


  • React vs Angular: NPMTrends 

The NPMTrends provide valuable information in terms of package downloads. From 2018 to 2022, React has a great rise in general package downloads. From 2019 to 2020, React touched 6 lakh downloads whereas Angular had downloads below 2 lacks. In 2022, React touched more than 12 lakh downloads, whereas Angular barely touched 3 lakh package downloads. These may be reason enough to think about the top React JS course in Kolkata.


  • React vs Angular: Statista Trends

The studies conducted by Statista Trends show that React remains in the 2nd position and Angular in the 5th position, with 43% and 23% share respectively. This was on the list of the most used framework by developers. So does this imply that you can go for the best react js course after the 12th? We shall get to it soon.


  • React vs Angular: State of JS Trends

The competition is stiff between Angular and React, even if you see differences in the statistics. The 2022 StateofJS trend for front-end frameworks, Angular and React, comes at the topmost position for consistent performance. React supersedes Angular in this scenario. Where React saw a raise in the graph, Angular saw a quick decline from 59% to 53% in 2019-2022. The trends point towards taking up job-guaranteed courses in React JS, but let’s not jump to conclusions yet.


  • React vs Angular: GitHub Trends

Experts and professional leaders who are enthusiastic about sharing their expertise with the communities where they reside and work are known as GitHub Stars. When deciding whether or not to believe in and use an open-source initiative, numerous individuals look into GitHub stars. Moreover, sometimes a repository’s star rating is used as the only metric for comparing or evaluating projects. React has significantly more stars on GitHub (146k) than Angular (59.2k).


Angular vs. React: Side-by-Side Comparison

Whether you take the angular certification course in Kolkata or React JS course elsewhere, do a thorough comparison study. Getting insightful knowledge with comparison studies can help you gain a better idea about the two. In this section, we give you key information about Angular and React in different aspects.


  1. Framework vs. Library

React is a library, while Angular is a framework. What is the distinction? Imagine an actual library to comprehend what a library in programming is. You go there to obtain information that has long been available; in another sense, you are not creating something entirely new. In programming, libraries function in the same way. They consist of a collection of pre-made layouts that you can use for your project. Nowadays, many universal sections of the code are identical for each programme. This is unlike in the past when developers had to write every line of code from scratch. For instance, any software can deal with images of a specific resolution, and any programme can use the code that facilitates dealing with these kinds of files.

A library is a set of such autonomous, distinct pieces of code that offer specific functioning capabilities for any software.

In libraries, single responsibility is the guiding idea. This implies that a library can only offer a single feature. There are limitations in React technology’s function in operating with user interfaces. This necessitates the employment of extra modules to do other operative tasks.

The function of frameworks is not restricted to a single task. Simply put, frameworks are a collection of libraries of several rules and functions to create a specific kind of application. The developer embeds the code into this as the foundation and architecture of the next programme. Thus, the framework dramatically streamlines development, saves time, and enables you to produce a finished product.


  1. Universality

One can use both technologies to create web and mobile applications. But to work on mobile development with Angular, one needs an extra open-source NativeScript framework. For React, one will need React Native an open-source cross-platform framework enabling you to create iOS, Android and UWP apps.


  1. Self Sufficiency

If you look at the definitions of library and framework, we can make a safe conclusion that Ract only lets developers work with designing the UI. React, by default, does not have the necessary tools to deal with web requests, routing or reforming state management processes. These functions need the installation of extra libraries. However, with Angular, it’s a different case. It does not require added modules and can easily deliver any kind of functionality within its means.


  1. Learning Curve

If you have concerns regarding the best React JS or Angular course after the 12th, this point may help you increase your clarity. Students often have confusion about which technology to choose. They mostly prefer as statistics show, React. It is not shocking at all. Because React does not include any extremely difficult features, it does not have as high an entrance barrier as Angular. To begin with React, developers should be familiar with JavaScript and other libraries used to create React apps (like Redux). On the other hand, you will need to understand numerous intricate functionalities to learn Angular.


Understand that Angular has a sharp learning curve because it’s a complete solution. If you want to master Angular, developers need to learn related concepts like MVC and TypeScript. To work with such a technology, one will need to learn several complicated and layered functions.


  1. Community Support

We have seen that React is highly popular than Angular. This is mostly due to the lesser barrier to entry. It is also because React gives far more freedom of action to people. React is constantly updated, thanks to famed corporations like Instagram and Meta, and is open-source. It has a large community of developers from several countries.


But what about Angular? Angular can’t show off the same recognition, mostly because of its complexities in learning. Though it has a big community that values the wide functions of this particular framework. Angular is an open-source platform similar to React. This means any developer can contribute to the development process in addition to the fixed development team.


  1. Ease of Update

As students, you must consider this aspect of both technologies, whether you plan to enrol at the top Angular course in Kolkata or React JS academy. Both React and Angular can get updated manually to the newest version. Still, for Angular, developers can install a command line tool called Angular CLI. It is a set of tools to swiftly update existing code, make new projects and add up libraries of third-party.


  1. Development Speed and Productivity

Should you know about the productivity and development speed of each technology? Yes, this will be crucial information for aspiring students deciding on React JS course or job guaranteed course in Angular JS. As experienced faculty, we can tell you that angular presents a fruitful and speedy development process. This is all thanks to the efficient usage of TypeScript language and command line interface. It helps facilitate real-time debugging.


The extra tools and technologies employed in the development, along with the amount of developer expertise, will determine how quickly React will develop.


  1. Performance & DOM

You should pay particular attention to the idea of runtime performance while discussing performance. This factor gauges how quickly the application can complete a specific task. To put it another way, it evaluates how rapidly your web application reacts to user input and actions. The quantity of DOM modifications directly affects how quickly your application updates the user interface and how intuitive it is.


React has the advantage of the virtual DOM technologies that we previously mentioned. Virtual DOM’s primary goal is to compute and reduce the number of questions and modifications on the real DOM, which will improve React’s performance.


There is no comparable method for interacting with the DOM in Angular. Performance may suffer while using a framework because the real DOM is frequently updated. The impact of performance changes by Angular’s bidirectional data binding. An observer is allocated to each binding, and at each modification, all viewers and all values connected to them are examined. It’s important to remember that there are other approaches to speed optimization, like the OnPush technique, to identify the component modification.


  1. JSX vs. HTML

If you plan to take up the best angular course after graduation, know that HTML is used for component markup in Angular. HTML, which stands for HyperText Markup Language is used to specify a web page’s structure. The browser gets a file document from the server by using HTTP or HTTPS standard via HTML. It then analyzes the elements of the incoming code to create an interface.


In React JS course you will learn that components in React are written in JSX. But this isn’t necessary. A JavaScript syntactic extension called JSX resembles HTML in appearance. By using the strength of HTML and JavaScript, you can develop components using this extension.


  1. App Structure

The MVC pattern is the foundation of the Angular framework. The core of this idea is to divide the application’s data into its Model, View, and Controller components. The “Model” offers data and responds to controller orders. When the model changes, the “View” component updates the user’s view of the model data. In response to the user’s activities, the “Controller” notifies the model of the changes needed.


React’s architecture lacks Angular’s rigid framework, which gives the developers a lot of latitude. But such architecture also mandates that developers create the structure from scratch for each new project. React’s data idea only includes a View component by default, thus incorporating a Model and Controller would need the use of other tools.


  1. UI Components

Angular and React are supporting an approach to development that is component-oriented. This method is predicated on the idea that a component is an autonomous module that may be reused. Utilizing UI elements that may be mixed and applied to other apps, the developer creates the app’s user interface.


Because Angular has so many pre-made design components integrated into its general operation, customising the UI is simpler and quicker when using the framework.


The community is embracing React slowly and steadily. New interface tools are frequently added to and updated in the library by React developers and made available for download through React portals.


  1. State Management

The State is a joint term for all kinds of information that’s valid to an app. Such a concept has both data, such as users or list of tasks, and also form state or loading state. The State can be global or local- this depends on the number of components utilizing it. Both React and Angular have a choice not to use added state management technology. But in some cases, developers may use state management libraries with particular libraries like NgRx or Redux.


Angular vs. React: Comparing The Salary

For any career aspirations, one has to think practically in every aspect of the chosen field. This includes salary information as well. When you think of the future, money is a crucial matter to think about. Whether you take up an ideal React js course or enrol at the best Angular JS training institute in Kolkata, take a look at the salary comparison for both-

  • In the USA, the average annual salary for an Angular developer and React developer is $80,000 and $120,000 respectively.
  • In Lithuania, the average annual salary for an Angular developer and React developer is $65,000 and $60,000 respectively.
  • For UK citizens, the average annual salary for an Angular developer and React developer is $75,000 and $71,500 respectively.
  • In Canada, the average annual salary for an Angular developer and React developer is $120,000 and $110,000 respectively.
  • The average annual salary for an Indian Angular developer and React developer is $10,000 and $9000.


You should know that salaries vary a lot because of an individual’s educational qualification, experience, location, company size and demand. Research these aspects to choose your field.

Angular vs. React: Vital Pros & Cons

Everything has its pros and cons, and the same goes for React and Angular too. Therefore, assessing both sides of technology would be sensible when choosing a career option. Here we list some of the prominent advantages and disadvantages of Angular JS & React JS.


Advantages of Angular


  • Flexibility- It is more flexible for developing web apps due to the usage of filters and directives. Therefore, filters are created as stand-alone functions that operate independently of your app but handle data conversions.


  • Testing- Angular JS is fully connected to Dependency Injection. All the regulators heavily rely on Dependency Injection. The unit testing for Angular JS is done by inserting mock data in the controller.
  • User interface- HTML is an illustrative language and is easier to understand. For this reason, it is used by AngularJS to define a web application’s user interface (UI). The basic idea is that you use attributes in your HTML, and these attributes describe what controller will be used for the component. It streamlines your web development procedure and helps you describe your requirements. AngularJS, however, takes care of all of the circumstances.
  • Security- Angular has an inherent security system to stop the most widespread HTTP weakness- cross-site script inclusion and cross-site request forgery. Developers can alleviate several security threats via Angular without having to write extra lines of code. But that does not mean the Angular app is completely immune to threats. It only means that the risks are lesser compared to React.


Disadvantages of Angular


  • Poor SEO-Despite having a great Angular group for the best Angular SEO, several developers and designers loathe it. They whine about the weak search crawlers. This is made clear by how single-page apps frequently modify their meta tag and content using the mighty JavaScript.


  • Backward compatibility issues- developers cannot simply switch from Angular JS to Angular. The Angular documentation contains a complete section that lists all feasible methods for handling migration.


  • Incapability with MVC- As a student, if you choose the Angular JS training institute in Kolkata, here’s something you should know. Angular will take a lot of your time if you follow the conventional methodologies and aren’t aware of the MVC architectural pattern.


Advantages of React


  • Extraordinary productivity- React creates its own virtual DOM (Document Object Model).It deals with all future developments in the Document Object Model as well as updates the Document Object Model tree. This gives it a flexible technique to handle getting a good display. From this point on, it eliminates excessive Document Object Model operations and reliably performs refreshes.
  • SEO effective- Even with improvements there, web search tools believe it is difficult to pursue JavaScript major applications. As a result, this has become one of the major problems with JavaScript systems. ReactJS, however, has done it well.
  • ReactJS components– DOM and Polymer JS have efficiently created lots of buzzes. They regularly make personalized elements and autonomous components. Developers can easily import these into a project.


Disadvantages of React


  • Poor documentation- Nowadays, you have to update your technology without which it may just stop working. With React, the technological update is happening so fast that there’s no sufficient time to create organized documentation. To solve this issue, developers write down the instruction themselves with the progress of new tools and releases in use.
  • The swift advancement-Progression is what we all need in today’s day and age, but it can cause some problems as well. Because of the swift advancement, developers have to be continually updated. They aren’t comfortable doing so regularly. It becomes difficult to adopt the new changes with constant updates.
  • JSX Syntax-It is through JS syntax that lets the designer uses HTML quotes. It also lets developers use HTML tag syntax for the delivery of subcomponents. JS syntax advances the all round composition of machine-readable code, thus giving the ability to compound parts in a single compile-time verified file.
  • Security-In comparison to Angular or any other modern web app framework, React has the smallest entry points. However, this does not imply that the React app is secure. It fully depends on its agility and capacity to work with external, open-source components. Because React lacks a variety of default security protocols or settings, this is where the privacy issue starts. Any React-based apps will probably exchange a lot of data between apps and APIs. It might cause private information to breach.


React vs Angular: The Trendy Apps

Several famed apps were made via React. You may be familiar with all the names and most likely can’t live without them in your daily life. The popular apps where React has been used are-

  • Facebook-Facebook, the app that changed the face of social media, utilizes React to some extent. React Native was used in the creation of the mobile application.
  • Instagram-This amazing technology is extremely important for a well-known React application. The technology behind the app’s features, including GPS or search engine precision, goes to Instagram.
  • Netflix-Netflix’s developers formally acknowledged in a blog post that they chose to React for its quick performance, setup, and modularity.
  • Airbnb-Airbnb is a global online platform for listing and looking for private short-term rentals. React technology is also used in the creation of such a platform that has boosted the travel industry phenomenally.
  • Whatsapp-The user interface of a revolutionary platform for daily communication was made using ReactJS.


The apps that have made their name through Angular technology are no less famous than React. Here are the names of the popular apps where Angular has been used are-

  • Upwork– The biggest marketplace for independent contractors, Upwork, leverages Angular to enhance responsiveness across gadgets.
  • Google-The maker of technology, Google phenomenally uses Angular. The entire population is dependent on it, and this one needs no explanation.
  • PayPal– As many as 300 million customers use PayPal every day to conduct transactions. Thanks to high-grade technology like Angular, developers created this extraordinary order placement and payment system.
  • Autodesk-Have you heard about Autodesk? Autodesk, the biggest provider of software for industry and civil engineers, uses Angular to build its website.


Angular And React Use Cases

The efficiency of both technical stacks for front-end development is equal. On the one hand, React can be used to create a unique application with specialised requirements. On the other hand, Angular has an advantage over React when it comes to creating feature-rich, complex applications.


When building applications like e-commerce applications, real-time data applications, streaming video applications, or user-generated content portals, Angular is the best option. Many industry titans have relied on Angular for the creation of their online applications. PayPal has the most helpful checkout process, Upwork runs smoothly, and Nike, Forbes, HBO, Localytics, and other companies have superb user interfaces.


Building data visualisation tools like dashboards, social networking sites, e-commerce or retail websites, or cross-platform smartphone applications is your best bet with React. The most trending and well-liked Netflix streaming platform, as well as, The NY Times, are both constructed utilising React.

React is also used by businesses like Dropbox, WhatsApp, Uber, and others for front-end development.

React or Angular- Which One To Choose? 

With all the facts, figures, definitions, comparisons, etc., in this blog, you may have had a slight idea about Angular and React. But when it comes to choosing a particular technology, it would be unfair to tell you which to select for your career as it will be fully your choice. Both Angular and React have their charm and usefulness. A framework like Angular has splendid and rich functionality, while React, a Javascript library, provides lots of freedom to developers.


Eventually, it is an endless debate about choosing between the two frameworks. React is like a cherry on the cake. The team, who are looking to build apps out of a small learning curve could use React. Whereas Angular is a perfect solution to create enterprise-grade apps.


Choosing between the two can make you anxious and hence doing a thorough study of both can give you some answers. Talk to experienced developers in this field to get updated facts about job-guaranteed courses in Angular JS or React.
