React is a Javascript library for creating user interfaces.
React is not a framework (unlike Angular or Vue, which have more opinions).
React is an open-source project created by Facebook.
It is based on components.
One of the most important aspects of React is the fact that you can create components, which are like custom and reusable HTML elements, to build user interfaces quickly and efficiently. React also streamlines the way data is stored and handled, using state and props.
