Typescript 5.1 is the fastest TypeScript yet 🔥
Crucially it allows typing of async React components 👍
TypeScript 5.1 is now out! Now with:
- smarter checks for undefined-returning functions
- no restrictions between getter/setter types
- better checks against JSX tags
- linked editing for JSX
- @param snippets
- new speed-ups
