I can sympathize with their issues. TS compiles are slow as fuck, and if I could find anything that was just as nice without the long compiles I’d switch in a heartbeat.
But I don’t think I’d ever want to go back to plain Javascript.
Not necessarily, TS issues are found in the editor which is where most of the use is. I don't test types only on compile but usually through VSCode itself.
