How to Choose Between ReactJS and AngularJS

JavaScript frameworks allow you to build dynamic and highly functional web apps, and AngularJS launched in 2009 is definitely on the top of this list. On the other hand, ReactJS – a library for creating interfaces released in 2013 – has become even more widespread over the last few years. This caused a massive debate: which framework is better? It seems like experts still can’t reach a consensus. When it comes to constructing your own site or application, you should pick the best tools. That’s why we decided to gather all available information on weak and strong points of each product and compare those in terms of structure, data-binding, efficiency, dependency management, and templating.


AngularJS is made to achieve big purposes and develop high-quality services. Surely, you will have to invest your time into learning AngularJS. This may be not the easiest tool to comprehend because of all those directives and controllers, but it is functional and helps you solve even the most complicated tasks. The framework is great for testing the final product and isn’t focused on particular development stages. It is capable of managing big data flow and boosting your server performance, so if you do everything right, you will eventually get an interactive and smart web app.

ReactJS is easy to use for almost any developer. It offers logical code writing and relieves you from mastering difficult procedures. It is also perfect to compose applications: components here perform as program functions, so the whole mechanism works plainly. This means, React JS saves you a ton of time, which can be essential if you work with a big amount of components.


One of the core advantages of AngularJS is two-way data binding that enables you to control all possible changes in the model and in the view. Thanks to it, your application runs much more effectively. However, a large data flow and number of changes might be difficult to monitor in the course of time. Again, you must get used to this tool and learn all functions it provides.

On the contrary, ReactJS implements one-way data-binding that allows you to track all the changes and keep those in order. In addition, it features ReactJS Native aimed at building mobile applications for iOS and Android. Another advantage of ReactJS is Flux designed for handling dynamic data. With the only one control point, ReactJS facilitates the performance of your product.


The performance of apps made with AngularJS is linked to the mentioned data-binding. AngularJS operates with real DOM, which means no matter who makes any changes: the database or the user. Likewise, changes in the model are immediately reflected in the view and backward. As a result, all your files are brought up to date without your help.

ReactJS, in its turn, works with virtual DOM. It changes the DOM tree with HTML code received from JavaScript components. This gives you an opportunity to draw a browser page again if necessary. Then, you can effortlessly utilize those features to the real DOM.

Dependency management

AngularJS utilizes Dependency Injection, so a developer is able to add services to his module. Thus, you can successively configure and test various objects modularizing. Besides, AngularJS includes the (toString()) function that finds all name variables of arguments and lists those.

ReactJS implements Inversion of Control for routing dependencies and ReactJS-di for Dependency Injection in components. Thanks to it, ReactJS handles dependencies much faster than AngularJS.


AngularJS enables you to build powerful directives though the syntax is quite complicated. It uses both templates and tree-method template logic.

Working with ReactJS, you merely imply template logic in a template.

In conclusion

So, what’s this all about? As you can see, AngularJS and ReactJS have certain pluses and minuses.

Now, it is your time to choose which framework fits you and your team the best.

We would say, ReactJS is simple library which provide a lot of flexibility and is easier to use for new and existing projects. AngularJS in turn is complete framework which most probably will remain framework of choice for large enterprises, though it is risky to use for 2.0 at the moment.
