ReactJS vs AngularJS : What is the difference ?

The increase in JavaScript tools and techniques is creating difficulty in choosing the right platform among developers and users. In this context, ReactJS vs AngularJS came into the limelight that shows the comparison between them. Moreover, the following write up explains the concept of ReactJS vs AngularJS in the real-time.

Here, we look into some differences among both the frameworks that will give a comparative study between ReactJS vs AngularJS and complete insight into the languages.

A brief history of ReactJS vs AngularJS

ReactJS is a free, open-source JavaScript library useful to build a UI for Single Page Application and responsible only for the view layer of the application. It provides a small and different piece of code called "components" that helps developers to compose difficult UIs easily. It came into public in the year 2013 for use.

AngularJS is also an open-source JavaScript framework useful to build a dynamic web page developed in 2009.  The latest version of Angular is 1.7.8 released in 2019 that is based on both HTML and JavaScript. It is also very useful for building a Single Page Application (SPA).

Features of ReactJS vs AngularJS

There are many features to compare ReactJS vs AngularJS depending upon various factors. ReactJS application is made up of different components. Each component has its logic and controls to apply. Moreover, these components are reusable and also help to maintain the code while working on larger projects. The ReactJS uses XML type language built on JavaScript and it is very simple and easy to perform.

AngularJS works on the “Model View Control” pattern for dynamic modeling. The MVC pattern in AngularJS is easy and versatile. Moreover, MVC makes it easier to build an individual client-side application. AngularJS uses HTML to make User Interfaces and also filters the data before it reaches the view. Furthermore, it provides various utilities for unit testing.


The deployment type between ReactJS vs AngularJS has some key differences. The ReactJS is an open-source JavaScript with external component libraries. This needs to be added to have the same number of features. The user has to add different elements to forcefully route one-way data flows, call APIs, set up tests, etc. Besides, if the flow of data is in another direction, then it requires some additional features to add.

The AngularJS provides several numbers of options and features that allow users to benefit from them directly. It makes possible to start a project faster than a startup.

The architecture of ReactJS vs AngularJS

The ReactJS works on the MVC (Model-view-Control) model. This refers to that the user has to use libraries like Redux, Flux, etc as a controller for navigation purposes.

The AngularJS is based on the MVVM (Model-View-View-Model). Moreover, it contains a list of tools and features. Such as data link, forms, routing, navigation, HTTP, and much more.

Real vs Virtual DOM

ReactJS creates its own virtual DOM where the different components give the comfort of movement within a web site. A virtual DOM object is the representative of the actual DOM object. Here, when the HTML document is loaded, the ReactJS makes a lightweight DOM from the JavaScript objects. It saves DOM on the server. It helps the application to run faster with no wastage of memory.

AngularJS works on the real DOM as it offers low performance with complex and dynamic applications. AngularJS’s MVVM model offers the advantage to reduce the load speed of web applications or web pages. When the user binds value within HTML with a model AngularJS creates an eye for binding to track necessary changes within the DOM. The communication is in the asynchronous mode that reduces the number of entries towards the server.

Scalability of ReactJS vs AngularJS

The ReactJS tends to test first and therefore scalable comparing to other frameworks. Moreover, using intuitive and attractive design and powerful Command-Line, the AngularJS is easily scaled high.

Data binding

The ReactJS follows a unidirectional or one-way data binding system. Here, the one-way data binding gives better control over the whole application. Moreover, it depends upon the flow of data. In case it is in another direction, then it requires some additional features. To implement a one-way data-binding flow in ReactJS, it has created its application structure called Flux. Flux helps to improve the quality and effectiveness of the codebase. Based on the above matter Flux is a great instrument while working with dynamically updated data.

Furthermore, the AngularJS follows a two-way data binding system. Here, the data automatically synchronizes between the model and view components. Besides, it helps to write less complex code to include the relation between components within the application. Thus, the two-way data binding is more useful for AngularJS.

Templates & Directives of ReactJS vs AngularJS

The ReactJS doesn’t support templates and directives division in its framework. It uses to write the template logic within the template itself.

Coming to usage of directives in AngularJS, there are many standard directives, like ng-bind or ng-app. These are useful to create own directives. The directives are the best way to organize the code around the DOM.

Dependency injects

This is one of the most important points in the comparison of ReactJs vs AngularJS. In ReactJS, it doesn’t offer an in-built container for dependency injection. There are some instruments such as Browserify, RequireJS, etc are useful to inject dependencies automatically in ReactJS. Furthermore, it is only possible with the inclusion of instruments such as Browserify, RequireJS, & ECMA modules.

In AngularJS, it automatically finds the suitable objects of injection with parameters such as $filter, $routeParams, and store. There are two major functions such as $inject and $provide that makes dependency injection possible in the AngularJS.

The ReactJS uses unit-testing features whereas the AngularJS framework uses Unit and integration testing system.

We can say that both AngularJS and ReactJS are great platforms for writing single-page applications (SPA). But both of them are completely different from each other. Some developers say that ReactJS is better than AngularJS or vice versa. However, it depends upon the usage of these instruments.

Summing up

In the above context, we had gone through the differences between the two frameworks ReactJS vs AngularJS. This makes the sense of using them in different areas that gives the benefit. Both platforms have their area of binding and action. It would be fair to say that ReactJS and AngularJS are two major platforms in this competitive industry. Moreover, in any industry, only the strongest part can survive well. So, we can say that both are the best technologies in the IT market. Hence, there is no talk about which one to choose, no one can go wrong by choosing either.

Moreover, it is in the talk that working with ReactJS seems a little easier. Because here the user writes JavaScript codes and builds an HTML environment around it. But there are some additional tools also need, such as Flux. Furthermore, AngularJS implements a different approach that works around HTML.
