React JS
React JS is a JavaScript Library for building an interactive user interface with fast rendering. It is built by the Facebook company. If we look into React's history, we see that, a few years, Facebook came across a problem related to its interface; it was not very responsive and lagged while displaying multiple feeds. To resolve its user interface issues, Facebook came up with this library.
React JS Library is used only to fulfill frontend design requirements. It is just involved with the view part of MVC architecture and doesn't support any server, web service, or API calls. To do backend tasks, such as API or web service calls, database manipulation, server file handling, and so on, you need to use some other library or framework, such as JQuery. We will cover the backend architecture in our next chapter.
Now, to understand React fully, let's go ahead and first understand its design and the key concepts and terminologies used in our later discussions.
