Difference Between – AngularJS vs ReactJS Framework

So, let’s learn the difference between React and Angular.

React vs Angular – Performance

Let’s have a look at React vs Angular performance.

Angular and React both are great for front-end development. Thus, very good at building large-scale apps. 

React.js uses a virtual DOM (Document Object Model). It allows you to access and change document contents, layout, and structure. On the other hand, Angular operates on real DOM. 

Suppose you want to update your user profile details like, for example, the last name. Then, the real DOM will update the entire tree structure of HTML tables until reaching the required data. In our case, it’s the last name. 

But, virtual DOM will update the changes without rewriting the entire HTML doc virtually. It renders much faster updates and performance irrespective of the app size.

So, Angular is a full front-end framework, but the real DOM slows down the apps while dealing with numerous data requests.  

Data Binding for Angular JS vs React JS

Data binding helps you to synchronize the data between business logic and UI. 

Angular uses both one and two-way data binding. The change in data impacts the view, followed by data change. In comparison, React uses the one-way binding. So, the developers often nest child components within higher-order parent components. 

Data Binding for React JS vs Angular JS

One-way binding brings more stability to the code. It also easies to debug an app built with React versus Angular. Yet, Angular one/two-way binding is simpler to work and is more flexible. 

Angular vs React – Component Architecture

React builds UIs by breaking them into components. You can create components that manage their state and structure them together into complex UIs. So, if your project is React-based, then you will need multiple integrations and supporting tools. They are-


It converts JSX into JavaScript for browsers to understand the app.


It’s a state container that speeds up React’s work in large apps.


It’s a standard module binder.

On the other hand, Angular is a pure, full-fledged framework that has many out-of-the-box features. 


It introduces the concept of reactive programming to JS.

Angular Universal

You can use it for server-side rendering.

Angular CLI

It is a powerful command-line interface.

Angular and React both have robust ecosystems. You can easily grasp React, but it needs multiple integrations like Redux to use it at its full potential. 

On the other hand, React is a library, so you can integrate it into any project even if it’s written in Angular.

Bundle Size of Angular vs React

Does the size matter? Well, the smaller the file, the faster it loads. Plus, the quicker it loads, the higher the ranking. Thus, ultimately increasing the conversation rate and margin.

Now, let’s compare Angular and React in terms of speed and size. 

Angular is larger. Hence, it leads to longer loading times and performance on mobile. React is smaller as compared to Angular, so it’s a bit faster.  

Backward Compatibility of Reactjs vs Angularjs

It is very important for developers that they provide a possibility to update architecture for adding new modules and libraries.

It’s impossible to jump from Angular 2.0 to 7.0. So, you have to install updates between the versions, one by one. 

But, React is a library having full backward compatibility. So, you can add various library releases to the application and update the older ones. 

Hence, if you plan to enhance your project step-by-step by adding new features, React is the best choice. It has absolute backward compatibility.  

Scalability of Angular vs React

Always keep in mind the future scope of the project while choosing a tool. 

As we discussed earlier, React heavily relies on third-party tools. So, it’s important to scale your app.  

However, you can easily develop a maintainable architecture with server-side rendering using React. Facebook, Whatsapp, and Instagram make use of React. They all are larger apps on a global scale. 

While Angular has all the core features, a developer may need to scale existing apps by adding new functionality. 

Angular vs React – Who is More Popular

So, who’s more popular in React vs Angular 2020 comparison? 

more popular in React vs Angular

Stack Overflow has named React.js the most loved and wanted web framework by developers (74.5%). Angular comparatively has a lower rate (57.6%). 

Rates on GitHub, Stack Overflow and NPM

Let’s have a look at how GitHub rates them first. 

React and Angular Rates on GitHub

That’s how it stands until March 2020. React has a clear victory over Angular by almost double a margin. But, it’s unfair to keep GitHub in view. So, let’s have a look at some other surveys.

NPM counts 53,647 dependents for React. It has weekly downloads of 8,140,830. So, it’s trending React. Then, what about Angular? Well, it isn’t impressive. Angular has just 1,609,139 weekly downloads and 10,128 dependents. 

We already discussed the Stack Overflow survey before. But, let’s have a closer look where nearly 90,000 developers took part:

  • Loved: React.js (74.5%), Angular (57.6%)
  • Dreaded: React.js (42.4%), Angular (25.5%)
  • Wanted: React.js (21.5%), Angular (12.2%)

React vs Angular Popularity Among Developers

React vs Angular popularity is again a hot topic of discussion among developers in 2020. 

According to the Stack Overflow survey, developers choose to React over Angular (React.js 31.3% and Angular 30.7%).  

Plus,’s survey details of 21,717 respondents is as follows-

  • React: 71.7% used React and may use it again (satisfaction: 89.33% for 16,099 users)
  • Angular: 35.8% used Angular, but may not use it again (satisfaction: 37.95% for 11,582 users)
react vs angular popularity

JetBrains’ survey of 7000 developers gives the following details-

  • React: 54% of users
  • Angular: 23% of users

Hence, we can easily conclude that React is a lot more popular among developers than Angular.  

AngularJS vs ReactJS – Popular Projects

Even the tech giants keep up with the trends, and their app developers use React and Angular both. Let’s talk about some of the world’s biggest projects. 

ReactJs Popular Projects

  • Facebook
  • Airbnb
  • Uber
  • Netflix
  • Instagram
  • Whatsapp
  • Dropbox

AngularJs Popular Projects

  • Google
  • Nike
  • Forbes
  • Upwork
  • General Motors
  • Telegram
  • PayPal

So, React, and Angular both are the best frameworks in the industry. But, you might wonder who’s better, right. Let’s find it out.

Angular vs React: Which is Better

Here’s the full comparison for React vs Angular-

TypeIt’s a JavaScript library and is much older as compared to Angular.It’s a complete framework.
Use of LibrariesYou can package it with other programming languages.It’s a complete solution in itself.
Learning CurveYou can grasp it easily as compared to Angular. But, it’s not easy to augment with Redux.It’s not easy for beginners. Thus, it needs a lot of training.
Community SupportIt does not offer much community support.It has a dependable and viable community support system.
Installation TimeIt takes longer to set up but consumes lesser time in coding.It may consume more time in coding but is easy to set up.
Testing & DebuggingIt requires a set of tools to perform different types of testing.You can test and debug the entire project using a single tool.
Ideal ForIt’s ideal for modern web developments and native-rendered apps for both iOS and Android devices.It’s ideal for developing large-scale and feature-rich apps. 
ModelIt works on Virtual DOM.It works on MVC.
Written inJavaScriptTypeScript
Language PreferenceJSX – JavaScript XMLTypeScript
Companies UsingFacebook, Instagram, Netflix, Pinterest, etc.WePay, Beam, Auto Trader, Mesh, Streamline Social, etc.
TemplateJSX + J% (ES5/ ES6)HTML + TypeScript
GitHub Stars180K80K
Adding JavaScript Library to the Source CodePossibleImpossible
RestrictionIt gives you an option to choose without any performance penalty.  It’s very sensitive and restricts you from using large models.
Use of CodeYou can manage the code according to the desired format.It has many ready-to-use elements but comes from a specific provider. So, there are priority collisions and namesDaces.
Data BindingIt uses one-way data binding. Hence, you can’t change the UI elements without updating the corresponding model state.It uses a one/ two-way data binding method. So, the model state automatically changes when you make any change.
DocumentationThe documentation is faster despite regular updates. The documentation is slower due to the ongoing development process.
