That's true... I come from a C# background so TypeScript looks very familiar to me. I just appreciate the flexibility and terseness of JS and I'm not sure there are always benefits to type-safety when weighed up against the cost of declaring it. Again it depends. In C# I feel it helps because the JIT or AOT compiler use it to make code, in TypeScript it has no benefit unless I abuse the underlying calls without understanding the implication (then we end up in a premature optimization argument).
I'm not seeking to be argumentative, I feel I learn something from the debate.
Actually types in typescript are just used to provide better tooling (better ide support kindof stuff)
