ReactJS

Facebook released ReactJS in 2013 and is already providing AngularJS with tough competition, although ReactJS is still more popular. ReactJS powers the user interface for both Facebook and Instagram, so it can build large, dynamic applications. It’s also the View component of the model-view-controller (MVC) software architecture.

ReactJS allows the programmer to develop a virtual Document Object Module (DOM), allowing the client and server sides to communicate more quickly. This capability is most useful for applications that require a powerful MVC View component without elaborate Model and Controller components. ReactJS is also beneficial for applications that need a View component for another front-end framework. Additional advantages of ReactJS include the resolution of some serious search engine optimization (SEO) problems.
