Unlike human beings, technologies lack the ability to fight with and kill each other. But the emergence of new technologies often affects the popularity and market share of conventional technologies. Both React and Angular are used widely by web programmers across the world.

A number of surveys have highlighted a steady increase in the popularity of React, along with a gradual decline in the usage of Angular. Angular is an open source JavaScript web application framework supported by Google. It provides features to simplify development and testing of single-page web applications.

On the other hand, React is an open source JavaScript library supported by a large community that includes both individual developers and corporate like Facebook and Instagram. It comes with features to simplify user interface development for single-page and data-driven web applications.

Many programmers prefer leveraging both React and Angular together to enhance the application’s performance and functionality. However, each user still needs to understand differences between React and Angular to pick the right technology.

Important Differences between Angular and React

Maturity: Angular released in 2009, whereas React released in 2013. Since 2009, Angular has been updated regularly to compete with other modern web application frameworks. React was originally designed as a component for Facebook. It is has been updated regularly to speed up development of data-driven and dynamic web applications.

Design Goal: Angular was designed with features to help single-page application development. The framework makes it easier for programmers to load new content without leaving the web page. On the other hand, React was designed with features to simplify user interface development for single-page applications. It helps programmers to create large applications that access and manage dynamic data.

Data binding and Flow: The two-way data binding supported by Angular makes it easier for programmers to make changes to the model automatically from any direction. But it requires programmers to write and organize the boilerplate code additionally. On the other hand, React implements a one-way reactive data flow that makes it easier for programmers to manage the document object model (DOM) without handling any boilerplate code. The data flow further helps them to create applications that can handle a large amount of data efficiently.

Code Packaging: Most developers want to deploy and run their code in a customized way. The custom packaging enables them to reduce the website’s loading speed by leading the bare minimums first. Angular does not provide any specific features to customize the code packaging. React does not require users to package the components of the application in any specific sequence. As it is a JavaScript development library, it can load various pieces of code dynamically. It further allows users to work with other solutions like web pack.

Debugging: Angular is designed as an event-driven framework. It allows developers to write code easily and quickly. But the users have to put additional effort to debug the code. The framework further required developers to rewrite the code in case the Angular directives do not work. At the same time, React makes it easier for programmers to debug the code by keeping the code written by the programmers separate from the code generated by it. The separation makes it easier for users to detect bugs and issues in stack traces.

Performance Control: While developing a website, programmers explore ways to customize and optimize its performance. Angular requires developers to count scopes to control the application’s performance. On the other hand, React allows users to tweak the application’s performance simply by creating custom functions. They can even create additional DOM to enhance the performance of the applications with a complex model.

Usage: Angular and React to accomplish different tasks and goals. They can use Angular to improve the application’s quality without putting extra time and effort. On the other hand, React helps them to create applications that deliver dynamic content or performs big data operations frequently. The programmers also have the option to use Reach and Angular together to boost the performance of various web applications. However, they need to handle both tools efficiently to avoid complexity within the application.

React can be used as a JavaScript library, whereas Angular is a web application framework. On their respective Github pages, Angular has more stars than React. At present, Angular has over 40,000 stars on Github whereas React has more than 30,000 stars.

The figure indicates that Angular is still popular and relevant as a modern web framework. It is always important for programmers to pick Angular or React according to specific needs of their project, regardless of their popularity and market share.
