AngularJS Vs ReactJS: Quick Comparison

The comparison between React vs. Angular is still a popular topic in the present day. React and AngularJS are both advanced, widely adopted JavaScript (JS) technologies, used to create interactive single-page applications. The number of JS tools for fast single-page application development is on the rise, making the choice of technology to rely on more challenging for us as web developers. This blog will have a quick comparison between AngularJS Vs ReactJS to build a dynamic web application. Let’s have a check.


Considered one of the most popular frameworks, Angular is an open-source Model-View-Controller application, resembling JavaScript. Built by a community of Google developers, the main usage of AngularJS is to build single-page applications, allowing to use of HTML as the base language and enhancing the syntax of HTML to clearly and succinctly articulate the components of the application


Developed by Facebook and its community members, the base of ReactJS are Javascript and JSX. As an Open Source JS library, ReactJS builds a dynamic user interface (UI) for Web applications with React components. When comparing Angularjs Vs Reactjs, ReactJS only provides the “View” in the MVC (Model View Controller). As a result, it isn’t as structured.

The key difference between AngularJS and ReactJS is its management. AngularJS has data binding by default, whereas React is generally augmented by Redux for smooth data flow and work with immutable data.


AngularJS provides a large number of native options and features, allowing you to benefit from several options directly. ReactJS is an open-source JavasScript library. Yed to add external component libraries and add elements for “routing” to force unidirectional flows, to call APIs, set up tests, manage dependencies, and more.

Data Binding

AngularJS uses two-way data binding, connecting the Document Object Model (DOM) values to model data. If a new value is provided to the app, it will result in the update of both the view and the model. However, the two-way data binding approach hurts performance. ReactJS supports one-way binding, providing singular behavior for your application. The implementation of dependencies helps the singularity to separate from the classes and the risks of error can be minimized. Debugging the app is easier in ReactJS


The base of AngularJS is the MVVM (Model-View-View-Model). It comes with an exhaustive list of tools as well as features like data link, change detection, forms, routing, navigation, HTTP implementation, and others. For ReactJS, you need other libraries like Redux and Flux as a controller or react-router for navigation.


AngularJS offers the advantage of the lesser loading speed of the web pages. Further, the communication is in asynchronous mode. reducing the number of entrances to the server. Since the visual interface is on the client-side, part of the back-end queries is removed. It improves the speed of designing web applications. ReactJS creates its own virtual DOM where components are attached, bringing the comfort of navigation within a website since all the data get displayed without refreshing the page. Also, virtual DOM enables the faster performance of ReactJS apps than AngularJS apps for applications of the same size.

Dependency Injection

Dependency Injection is a software design pattern that helps in making components reusable, maintainable, and testable. AngularJS automatically finds the appropriate injected objects with parameters such as $routeParams, $filter, store, and $scope. However, the built-in container for dependency injection with React is missing but made possible by the inclusion of instrument modules, such as Browserify, RequireJS, ECMAScript 6 modules.

Directives And Templates

AngularJS has its directives to work on DOM, like ng-bind or ng-app. You can even create your directives as well, making it one of the most powerful ways to work with the DOM. We can use directives, both standard and specific to bind DOM elements with AngularJS applications. ReactJS do not offer any division into templates and directives or template logic. The logic is required to be written in the template itself and it chooses to reinterpret all templates and the UI every time an event occurs.


With its intuitive design and powerful CLI, AngularJS is easy to scale. React is testable and therefore scalable compared to other frameworks like Vue.js.

Angular and React are excellent choices for building robust and secure applications. While several different and conflicting opinions exist, everything depends on your project goals, business objectives, and technical expertise.
