> Flow is not a transpiler, there is no concept of "emitting code", only of stripping away the annotations. In contrast, TypeScript is a transpiler.

TypeScript is a transpiler to the extent you want it to be a transpiler. You can use it to remove annotations only with '--target ESNext' - then it works the same as Flow does in your use case and does not add anything.

In the same vein, most people use Flow with babel. Then it's "transpiling" in the same way TypeScript is "transpiling".

You're either severely misinformed or opting to make your argument by misleading. I wonder how much you have actually used TypeScript.
