AngularJS vs ReactJS: Which is Better?

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

Here, we have made a detailed comparison between Angular.js and React.js, so that you can choose the best one for your project.

Before moving ahead with the comparison, let’s quickly go through the latest statistics of AngularJS vs ReactJS.

Let’s first check, what google trends say about AngularJS and ReactJS:

AngularJS vs ReactJS - Google Trends
  • As per trends.builtwith, more than 4,105,780 websites are running on AngularJS and 10,468,256 websites running on ReactJS.
  • There are 1,533 ReactJS contributors and 1,703 AngularJS Contributors on GitHub.

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

AngularJS Vs ReactJS: Framework Vs. Library

Besides above statistics, 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.

Both frameworks are used for developing awesome web and mobile apps. AngularJS has remained in the list of Top 10 Javascript frameworks since its release in 2010. While the popularity of the ReactJS is increasing exponentially from the last few years.

AngularJS became popular among developers because of the Model View Controller Framework. As of now, React is even widely well-known 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)?

You will find answers to all these questions from our blog, so rest assured.

In general, Choosing a proper front-end application development technology for your project depends on the end-user agreement.

You can also discuss your doubts about the project with front-end developer. to ensure you are going in the right direction from start.

Apart from this, let’s quickly check the below table given below to clear some basic doubts about both the technologies:

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 support is one of the most essential benefits which make Angular one of the leading Javascript frameworks. AngularJS Developers 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.

Winner: Here, the clear winner is AngularJS, as it has better community support than ReactJS.

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.

Winner: Again Angular.js is Winner because it offers numerous native options.


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.

Winner: AngularJS is the clear winner here as it provides developers better 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.

Here, you don’t need to create a method to monitor any code and update JS code as per needs. One of the hindrances of two-way data binding is that it affects the performance of the app. How?

AngularJS builts a watcher for every binding. Hence, at a certain stage in development, your app will be jam-packed with a lot of watchers to limit the elements.

Unidirectional Data Flow

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, to another, mainly called a dispatcher. Flux’s dispatcher acquires an object and sends it to a proper store, which then updates itself.

As soon as the update gets over, view updates accordingly and forward a new action to the dispatcher. Now you can transfer an action to store as soon as it gets modified. With this idea, Flux enhances the potency of the codebase.

Winner: Angular.js is the winner as it’s quick to work in two-way data binding. While ReactJS is useful to make code stable and debugging fast.

User Experience

AngularJS uses a 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.

Winner: React.js is the clear winner between AngularJS vs ReactJS as it allows developers to update a specific part of the application.


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.

Winner: ReactJs as it gives better performance as compared with the AngularJS as it supports virtual DOM.

Dependency Injection

AngularJS consists of an inherent dependency injection subsystem that enables developers to build, understand and test the applications effectively.

Dependency injection supports making components reusable, maintainable, and testable. AngularJS instantly finds all the injected objects using parameters like $routeParams, $routeParams, $filter, store and $scope.

Moreover, there are two essential functions known as $inject and $provide that are highly-responsible for marking dependency injection possible.

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.

Winner: AngularJS works well in terms of dependency injection as compared to ReactJS because it offers various parameters.

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.

Winner: AngularJS functions better than ReactJS as it offers different directives & templates.


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.

Winner: Comparing AngularJS vs. ReactJS in terms of testing, ReactJS is the clear winner as it supports quick testing.
