Types in JS?

Apr 4, 2022
This discussion dives into a new proposal for optional and erasable type syntax in JavaScript, comparing it with traditional typed languages. The evolution of type systems, driven by the complexity of apps, highlights how tools like TypeScript enhance productivity.

The conversation also touches on the challenges faced in implementing a type system and the desire to integrate JSX and TypeScript directly into browsers.
