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.
I'm also not a very big fan of static typing, but the person is coming from Java so, Im expecting typescript would be easier transition for him

Actually types in typescript are just used to provide better tooling (better ide support kindof stuff)
