What I love about TS is that it's up to me how much effort I want to put into the type system. I find that I end up using TS even for very small projects, because I can use it for only 'the important' bits.

That said, my background is mostly Ruby/Python/JS/PHP, so for all I know this is true of many statically typed languages (but from what I read this is not the case).

Still, for those with a background similar to mine I can highly recommend TS as a great starting point for more statically-typed code, precisely because it's opt-in if you want it to be.
