I'm looking forward to this. But it does amaze me how Microsoft with all it's power takes years to complete the port to a different language and bun does it in 7 days. Crazy times

That made me wonder, since bun natively supports typescript, is it already using some kind of rust implementation of typescript?

Bun does zero work in relation to TypeScript's type system. Since it's a strict superset, it is "simply" stripping types to execute the resulting JavaScript. That is effectively what it boils down to.

TypeScript is the most complex type system in existence. I am unsurprised it is difficult to port, but I am still a bit surprised by the length of the project thus far.

Probably because TypeScript is too important to leave it purely to AI. The gall to question Anders Hejlsberg :D
