The discussion/debate about whether AngularJS is better or React JS is better is something that has been happening for a considerable amount of time. It is an undeniable fact that both are robust technologies. Rather than putting it as Angular JS vs React JS it can be stated as Google vs Facebook. It is because Angular JS is maintained by Google and React JS is maintained by Facebook and its communities. If there is a requirement to build an advanced and customized web applications, these two are the most preferred ones. This article will provide you a comparison between Angular JS and React JS.

The Framework

The web and mobile applications play a very curtail role in the tech ecosystem.  Considering the framework of both Angular JS is the clear winner because it has proved its mantle by handling highly complex websites. At the same time, we cannot jump into the conclusion where something negative about React JS because it has to withstand the time test. The management factor is the one that is making a huge difference. In Angular JS data binding is bundled by default, but React JS it is augmented by  Redux which gives unidirectional data flow.

The Implementation

One of the features that stand out in Angular JS is native features and options that it offers. With the already available options, it is easy to start the project faster because there is a good possibility that you will find your requirement. Since React JS is an open script library one needs to add some external components to the library to have features like AngularJS. Even elements like call APIs, routing to force unidirectional flows, dependency management, tests set up and a lot more.

Data Binding

AngularJS uses a two-way data binding method. This actually connects value to model data with the Document Object Model. By using this method the user interaction with the field any new value that is provided will result in updating the view and as well as the model. This way of data binding helps to write less boilerplate code. Entirely contrast to that React JS supports one-way binding. The one-way data flow in React JS controls the complexity. Comparing to Angular JS it is much easier to debug the self-contained components.


The architecture of AngularJS deserves a very special mention. It is based on Model-View-View-Model. It comes with more number of tools as well as features. Some of them include data link, change direction, form navigation, HTTP implementation and a lot more. That is not the case when it comes to React JS because other libraries like Redux and Flux need to be used as a controller.


There is an evident difference when compared to the loading speed of Angular JS and React JS. The MVVM model of Angular JS drastically decreases the loading speed and hence it has the upper hand. One of the important aspects is that communication is in asynchronous mode. The server entrances are reduced. A part of the back end queries are removed because the visual interface is one the client-side. The Virtual DOM of React JS is the place where the components are attached. The navigation within the site is made easier. Without refreshing the page all data is displayed and hence the flow of the site is fast.

Dependency Injection

Dependency Injection pattern is the one that helps to make the components reusable and testable. AngularJS has the capacity to automatically find the perfect inject object. Some of the parameters include route params, filter, scope, provide, inject and store. One of the major differences between AngularJS and React JS is that in React JS there is no built-in container that can carry out dependency injection. For dependency inclusion instrument modules like ECMAScript, Browserify, and Require JS must be included.

 Directives and Templates

The directives of AngularJS is to work on or ng-app. These two are standard directives with it. The best part is that your own directives can be created. It is considered to be one of the most powerful ways to work. These directives can be used for standard and specific -binding DOM elements with applications. The template logic has to be written in the template itself. Every time an event occurs all the templates are reinterpreted.


Scalability is one of the important parameters that need to be taken into consideration. Especially in the world of technology scalability is not an option it is mandatory. With a design that is so intuitive and a powerful CLI way beyond levels of comparison, Angular JS is a lot scalable when compared to a React JS. If you are taking testing as a parameter React is very much testable and hence it will win the race with other platforms like Vue.js.


Although both Angular JS and React JS have different philosophies of application development they have great support from their community. Considering the features mentioned above it is not a very easy choice to make.

If you are considering flexibility then React JS is the ideal choice. If efficiency is what you are looking for Angular JS is what you need to opt for.
