Summary

React is an open source JavaScript library developed by Meta (formerly Facebook) to build a component-based interface. React works declaratively: you describe the view for each data state, and React updates the DOM to fit. The core concept covers components, JSX, virtual DOM, as well as one-way data flows.

Key points

React was developed by Meta and released as open source in 2013
React uses a virtual DOM to minimize the manipulation of expensive DOMs.
Data flows one way from parent to child through props
React only handles the display layer so it can be combined with other libraries.
