What is React?

React is an open-source JavaScript front-end library developed by Facebook for building interactive user interfaces and web application front-ends. Released in 2013, React aims to simplify the development of complex, changing data flows in web UIs.

React builds on basic HTML/CSS/JS to provide a declarative component model. In this model, UIs are broken into encapsulated, reusable pieces called components. These work similarly to Lego blocks snapping together to form complex UIs.

Components use a templating language called JSX that resembles HTML to render content, can have a local state, and update dynamically in response to data changes. Events triggered from one component bubble up to notify parent components automatically through a unidirectional data flow paradigm.

Virtual DOM tracking of changes combined with selectively re-rendering only components that change enables very high performance compared to raw JavaScript ops. React can thus power data-intensive apps like Facebook and Instagram that show constantly updating content flows.

React promotes loose coupling between components and thinking regarding simple, reusable interfaces over concrete implementations. Components also have lifecycle methods like componentDidMount(). Additional libraries like React manage routing in single-page apps.
