React Catch-up

Don't get overwhelmed, get caught up quickly!

React has changed more in the past few months than the past five years it’s been around. Most of the changes are about getting our apps ready for Async React.

These short, easy to understand lessons, will help you navigate the changes.

Topics include:

  • setState updater signature
  • componentDidCatch and ErrorBoundary
  • getDerivedStateFromProps
  • getSnapshotBeforeUpdate
  • componentWillMount
  • componentWillReceiveProps
  • Fragment and returning arrays from components
  • refs (all three of them πŸ˜…)
  • forwardRef
  • createContext

Hey! I've been building stuff on the web since the 90's (before fancy things like CSS and JavaScript!). I care most about great composable APIs and accessible UI. I co-authored React Router and now build OSS at Reach. I've taught web development and React to thousands of developers at our workshops, and now we're bringing that material online.
