👀 Is this Flow, or TypeScript? Is Flow coming back? - Flow syntax aligns with TypeScript - Flow has pattern matching - Useful React hooks/component/renders syntax - Compiler has been recently ported to Rust I'll keep an eye on it for you, but this is promising!

JavaScript Pattern Matching with Flow

No more switch! match expressions and statements bring exhaustiveness, destructuring, and readable branching together in one construct.

The render types section of the blog post doesn't even go all that in depth. This is contrived for the sake of conciseness but really pay attention to what this code is expressing and understand how buck wild it is that we can express this with complete type safety!

Nice new errors! My only tweak would be to change: src/components/calltree/CallTree.js to src/components/calltree/CallTree.js:53 Because then I can directly click in my terminal to go to the offending line in my editor.

Working on new @flowtype and @typescriptlang targets #apollocodegen and it's coming together nicely. Can't wait until its production ready.
