Typescript is another language. It kind of goes without saying that people using a different language be more likely to use something if it were in the language they use, doesn't it?
I mean, by any reasonable definitely of a language, Flow is another language too.
Typescript aims to be a superset of ES6+, with all valid Javascript also being valid Typescript (at least syntax wise).
So while it is another language, it is very much related.
Awesome that this exists already. Now we just need TypeScript support... :)
clang-format supports TypeScript and has a VS Code plugin. (See my other comment in this thread for some discussion of the differences between the tools.)
I may need to check that out. Thanks for the link!
