React.js is an efficient, declarative, and flexible open-source JavaScript library that is useful for developing user interfaces specially for single page apps. With React.js, users can build complex user interfaces from “components.” Components are small and isolated pieces of code.

React.js can also be used as a base in the building of both mobile and single-page apps. Although, complex React.js apps usually require additional libraries for interaction, routing, and state management with an API (Application programming interface).

React.js makes it possible for developers to design large web apps which can change data, without reloading the page.
