  • TypeScript

    TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

    • I just tried this and I really like how guards can operate on the input type, so you can do stuff like, if an input is A | B the output is B. This is something I wanted to do, but it's not possible if guards are wrapped in a class. I even opened an issue for this very reason.
