I would endorse that. TypeScripts's type-system soundness holes kill the fun with that language very quickly, imho. That was a really big disappointment for me. A "static" language that compiles fine and than crashes at runtime with complete WTF-bugs is not much better than a dynamic language. You just can't trust the compiler and need to double check every line of code anyway. So there is not much additional value in this kind of "type safety". I would prefer Rescript of Scala.js anytime to TypeScript. Got really disillusioned by TS.
