AngularJS vs ReactJS: Which is Better?

AngularJS vs ReactJS: Which is Better?

Are you confused about whether you choose AngularJS or ReactJS for your next front-end development project? If yes, then you have reached the correct place.

To clear all your doubts regarding the same, we will provide complete guidelines on the difference between AngularJS and ReactJS. Stay with us till the end to get a clear idea.

Before choosing a framework, understand all the requirements of the project from start to finish. Each framework has its own strengths and weaknesses.

Therefore, we highly recommend you select a framework only when you have a complete understanding of the same.

Before moving ahead with any of the frameworks, let’s have a quick look at the statistics:

Let’s first check, what google trends says about Angular and React:

Let’s have a basic introduction about both the frameworks:

AngularJS Vs ReactJS: Framework Vs. Library

AngularJS and ReactJS comprise a great community, which you will not find in other frameworks. Both are highly advanced and globally accepted JavaScript technologies that can be used to develop interactive single-page applications (SPAs).

Also, a wide number of libraries and tools are added constantly, which makes it challenging for developers to decide which technology to use for the project.

There are many leading companies using both ReactJS and AngularJS. We are talking about some of the most reputed brands across the globe which are listed below:

Popular Mobile App Development Frameworks

AngularJS become popular among developers because of the Model View Controller Framework. As of now, React is even widely popular among JavaScript developers even though it’s just a library.

React library only comprises view and doesn’t possess model and controller components. Then, how it become so popular? How can we compare a framework (AngularJs) against a library (ReactJS)?

Choosing a proper front-end application development technology for your project depends on the end-user agreement. You can also discuss your doubts regarding the project with front-end developer. Apart from this, below table will clear some basic doubts about both the technologies:

Latest Stable Version (as of 25th Sept 2019) 1.7.8 16.8
Best for Best for SPA that update single view at a time Best for SPAs that update many views at a time

This was just an overview of AngularJS Vs. ReactJS. Now, here we will provide a detailed comparison of AngularJS Vs. ReactJS.

AngularJS Vs. ReactJS: The Complete Comparison

Global Community Support

Worldwide community for support is one of the most essential benefits which make AngularJS one of the leading Javascript framework. AngularJS Developers as well as designers regularly collaborate and contribute to the community, thereby helping to improve the authenticity of the network.

Even though the popularity of ReactJs is increasing continuously, ReactJS developers face issues as there are fewer contributions and collaborations.

Quick Implementation

AngularJS framework provides a lot of native options and features. Hence, you will be able to choose various options instantly. This will help you initiate the project without being overwhelmed by the number of choices you take during the startup.

In ReactJS, you have to take the support of various external component libraries to get the same features as AngularJS. For this, you have to add elements of routing, call to APIs, manage dependencies, etc.


In-Depth documentation in AngularJS is responsible for strong communication and collaboration among various developers. But, one has to spend more time in understanding all the stuff.

Issues of poor documentation points back to the constant release of tools. Even though, it comprises libraries like Redux and Flux, which helps to improve the react ecosystem. Various developers believe that React Technologies are changing too fast that they are not getting time to write proper documentation.


AngularJS utilizes a two-way data binding that binds Document Object Model(DOM) values to model data. This shows that whenever the user interacts with an input field and initiates a value to the app, then both view and model will be updated. This will further help you write less boilerplate code to make interactions between the components of the app.

ReactJS supports one-way data binding. It offers singular behavior for your application. Hence, you can easily know where data is changed. This also helps to reduce complexity. Also, it is simple to debug self-contained components of big React apps as compared to big AngularJS apps.

If you want to enable the unidirectional flow of data in React, Facebook has built its own app architecture known as Flux. Flux manages the flow of data from one end, mainly called a dispatcher. Flux’s dispatcher acquires an object and sends it to a proper store, which then updates itself.

User Experience

AngularJS used Real DOM. Here, whenever a user updates anything in the single data structure, then it will be affected in the entire tree. This is useful in some cases, while troublesome in other cases.

As compared to other frameworks, React uses Virtual DOM, which is an abstract form of Real DOM. It gives ReactJS app developers an opportunity to update the changes made by the users in the app without affecting any other parts of the interface.


AngularJS creates a watcher to look after all the modifications done in DOM. When view starts getting updates, AngularJS compares the newly obtained value with the old ones. The main issue here is that it checks all the values that are changed along with older values that are tracked via watchers.

ReactJS consists of virtual DOM which enables building light DOM tree and saves it to the server. When a user interacts with the website, for instance filling a form, Reacts builds a new virtual DOM and compares it with the earlier saved DOM.

After this, the library finds all the things that are different between the two models and creates a virtual DOM again, however with a changed HTML. This complete process is done on the server, which reduces the load on the browser.

Dependency Injection

AngularJS automatically finds appropriate injected objects and components such as factory, value, constant, service, and provider using parameters like $routeParams, $filter, store, and $scope. Dependency injection is possible in the AngularJS framework with the help of two components: $inject and $provide.

React doesn’t provide any option for a built-in container for dependency injection. However, you don’t have to find any way to inject dependencies instantly in your react project. You can take the help of some tools to inject dependencies instantly in a React app. Some of these instruments include Browserify, RequireJS, EcmaScript 6 modules that you can use through Babel, ReactJS-di, etc.

Directives and HTML Templates

AngularJS comprises its directives to work on DOM. The two most standard directives present in AngularJS include ng-bind and ng-app. Also, you can build your own directives as well. In short, you can use specific and standard directives to bind DOM elements into AngularJS apps.

AngularJS utilizes plain HTML templates, which is a great thing. Moreover, these templates are passed to the compiler via DOM elements and not as strings. This one thing helps in better workflow. Also, this helps in quick manipulation, extension, and reusability of templates.

Unlike AngularJS, ReactJS doesn’t provide any division into templates and directives or template logic. Here, template logic should be written in a template only.


In AngularJS, testing can be done with ease due to its in-built testing functionality. Also, one can perform testing using tools such as Karma and Jasmine. Components testing can be done with ease due to incorporated dependency injection into the structure.

ReactJS widely uses Redux, which reduces the task of storing and managing component states in big complex applications with a lot of dynamic elements.

It gives a chance for developers to add application state in a single object and allow all the other components of the app to access the application state without affecting child components. Hence, it quickly tests application and log data changes by using hot reloading and other tools.
