Your comment neglects to mention that Typescript debugging is generally easy because one of the design goals of typescript is to produce javascript that matches what a developer would write.
Debugging javascript produced by Babel is generally hell in comparison. The transforms done by Babel are not designed to be human readable and they generally aren't.
Whoops, you are right. Removed the misleading part of my comment.

Only Facebook doesn't care much to back or promote Flow, besides the occasional blog post, whereas Microsoft has created a whole IDE / VS Code support for it, great tooling, documentation, etc.
Moreover, Flow is pure annotation, which can be removed by Babel. And Flow is also backed by a large company (Facebook instead of Microsoft).
However, if you do want to generate JS, use a language that elminiates runtime errors almost completely, such as Elm or OCaml (through bucklescript or js-of-ocaml).
[1] The following presentation contains some scary examples of incorrect code not rejected by Typescript. I'd rather prefer Flow which errs on beeing too strict: https://djcordhose.github.io/flow-vs-typescript/elm-flow-typ...
