React
What is React
React (React.js or ReactJS), released in 2013, is a popular JavaScript library.
It was developed by Facebook and designed for highly interactive single-page applications (SPAs). It is a front-end library, specifically focused on building dynamic and highly-responsive user interfaces for web applications.
Reactis optimal for fetching quickly-changing data that needs to be recorded. As such, it is used as a base for the development of mobile or single-page applications.
Unlike AngularJS, it uses one-way data flow, making code stable. This feature makes React a fairly popular front-end programming language.
