ReactJS in 30 seconds

React is a JavaScript library that aims to help us write user interface(UI) code. React’s fundamental building block is the Component which, in its simplest form, is a JavaScript function that generates UI code (usually HTML). The generated UI code is then rendered by the device. A Component represents a small portion of the UI. Many Components are used together, or composed, to create entire views or applications. React Components can receive data that is used to generate the UI code. Whenever a Component’s data changes, it will automatically regenerate the UI code.

@ross — big fan of these "in 30 seconds" type of posts. We might need to supplement the #explainlikeimfive tag with an #in30seconds one.
