Slightly off-topic, but I really hope that Typescript and Flow(type) can standardize on a type annotation syntax. There are tons of libraries that have annotations written either inline or provided third-party for one or the other, but the existence of two competing syntaxes fractures the community and tooling possibilities. The capabilities and visions of Flow and Typescript are pretty similar[0][1], so I think there's a real possibility of standardization. It also appears that Flow is, at a minimum, intending to support the automatic conversion of Typescript definitions to Flow[2], which would be a good start. A convergence in the two standards would also potentially open the door to a typed-ECMAscript official standard, which would allow for improved tooling, greater support in libraries and transformers, and eventual browser adoption.
