It seems like a lot of JS developers are finding shelter in TypeScript and Rust. I think this is good news. TypeScript has an awesome type implementation on top of what we already know, and Rust obviously has huge performance benefits over JS. I'd not had much strongly-typed or compiled language experience before, but recently started using both simultaneously for a new project and it's really been a great learning experience and stepping stone. I chose Rust over the team's familiar C++ for deterministic and stochastic model simulations and now they loathe working on former projects. The transition to TypeScript for those of us who were primarily web developers was pretty seamless and the exposure certainly made understanding features of Rust, etc. a lot easier. I don't really see any serious negatives in this move. If the likes of Rust and Go pull more web developers into the world of safer and more performant languages and systems, what's the issue?
