Thats weird, the best ppl in JS seem to be tearing TS out due to compile time/toolchain perf problems.

Do you have any large typescript projects?

I personally hate everything about the transpilation step; the time it takes (slows down dev-test iteration by a lot), the source mapping aspect, debugging in a live production environment (I hate having to debug transpiled/mangled JavaScript). I hate having to handle multiple permutations of engine versions (too many possible permutations of tsc and node.js version numbers which introduces configuration and setup difficulties; it rarely works out of the box; it's a nightmare for open source projects when you're potentially dealing with a broad range of different operating systems and environments which you have 0 control over; maybe the user needs tsc version x.x.x for some different reason and you cannot force version y.y.y onto them!!! So their tsc version will not work with your tsconfig)... It just adds a ton of bloat, dependencies (security/maintenance burden), setup/compatibility problems and the value it adds is marginal.
