Intro

React is an open source front-end Java Script Library (Not a framework). It’s widely used for developing User Interfaces and UI Components. Jordan Walkie an Engineer from Facebook has developed the initial version of React. It is maintained by Facebook and Individuate Developers community and Companies.

How does React Work?

Instead of manipulating the browser’s DOM directly, React creates a virtual DOM in memory, where it does all the necessary manipulating, before making the changes in the browser DOM. React finds out what changes have been made, and changes only what needs to be changed.

A React application is made of multiple components, each responsible for rendering a small, reusable piece of HTML. Components can be nested within other components to allow complex applications to be built out of simple building blocks. A component may also maintain an internal state — for example, a TabList component may store a variable corresponding to the currently open tab.
