No experience of Flow, and I hear all of the opponents of these "superset JavaScript" solutions who lament their inability to really tighten up the language in a way that a true static language would. However, JavaScript is clearly going nowhere anytime soon, and whilst WASM has the ability to change the state of play, I've found adopting TypeScript in general to be hugely beneficial. It's 100% fair to point to all of the things it doesn't provide, or indeed the way that it tries to make JS out to be some classical OOP language which it's not, but it's helped me track bugs and refactor code in ways which would never have been possible without it, and for that I'm grateful. In comparison to other tools such as mypy, TypeScript is light-years ahead in its general ease of use and community support.
