React.js: The Documentary
A documentary about React came out!
It tells a story of how Facebook engineers created an internal framework called Bolt, but it wasn't scaling very well. Then, Jordan Walke, Facebook Product Engineer working on Ads, came up with some ideas on how to improve Bolt and make it more functional. The new framework was supposed to be named FBolt. Its idea was to re-render the whole UI whenever state changes.
This is how React was first born!
