Top companies have used Angular and React.Js both due to their high performance. Also, Angular and React.Js are based on the same programming language, i.e., JavaScript. Now, let’s dive into their basic features, with their common pros and cons, before choosing a better one for your project. 

What is Angular?

Angular is a JavaScript framework for building high-performance and dynamic mobile and web single-page applications (SPA) and making application components clear and concise. It was developed on October 10, 2010, by Google. Its version is 1.8.3, released on April 7, 2022. 

Features of Angular

Angular app development has many great features. Some are:

  • Allows the developers to use JavaScript cleanly using the Model View Controller (MVC) approach. 
  • Makes the application size small and doesn’t require a heavy installation setup and additional library. 
  • They are mainly used for building Single Page Applications (SPA). 
  • They are used for both Mobile as well as desktop applications. 

What is React.Js?

React.Js is a JavaScript library that has gained popularity briefly due to its great features. It is used for front-end Web application development and is open-source as well. Facebook developed it on May 29, 2013.

Features of React.Js

React.Js app development offers some fantastic features, which are below:

  • It makes the application size small with reusable components, which means one component can be used again in the same application. 
  • Saves memory by supporting virtual DOM. 
  • Time efficient, with cross-platform compliance. 
  • Makes the application process simple and can work well with other frameworks. 

Angular App Development

Many top tech giants use Angular app development for building dynamic apps. Below we have mentioned a few of its examples: 

  • Weather Applications like
  • E-Commerce i.e PayPal.
  • User-generated Content Portals (
  • Video Streaming Application (Netflix).
  • Travel Application (JetBlue’s application).
  • Banking Application (Santander).

React.Js App Development

Many top web and mobile applications are built using React.Js and run smoothly on all browsers as it supports cross-platform. Those are:

  • Instagram 
  • WhatsApp 
  • Facebook 
  • Dropbox 
  • Pinterest 
  • Yahoo! Mail
  • Codecademy
  • Reddit

Pros of Angular

The Angular app development has many advantages, e.g.:

  • Cross-browser means it can be efficiently run on any browser. 
  • More functionality can be achieved using short code, making the application concise. 
  • Supported by a large community, i.e., Google, it is ideal to use with easy-to-test individual components. 

Pros of React.Js

React.Js app development offers the following benefits: 

  • The React.Js JavaScript framework converts the virtual components into DOM for faster performance. 
  • No need to learn another new language for React.Js. Anyone with prior knowledge of JavaScript can quickly move towards learning its library, React.Js. 
  • Good community support and time efficiency. 

Cons of Angular

Angular app development also has some disadvantages, like it is less secure as there is no server authorization while using it. Also, it is complex and vast, so there is no specific way to perform the task. The other one is it is solely based on JavaScript, which means if an app’s JavaScript is disabled, nothing will be rendered.

Cons of React.Js

The top con of React.Js is it is only used for UI, meaning for React.Js app development; you need other technologies too. Also, there is no proper documentation of React.Js due to its continued update. As the React..Js JavaScript framework is used for front-end development, it can’t process data itself. 

Which one is better to choose: Angular vs. React.Js?

Well, this is a tricky question, and once again, we can say it mainly depends on your application. If you want complex functionalities in your application, like a native web app with higher productivity, then it’s better to opt for Angular app development. But if your app is custom-made and you need to update its code occasionally, React.Js app development would be a good choice as it offers reusable components.
