Awareness just means "have heard of it". 99% have heard of Coffeescript but 14% want to use it in the future. 98% have heard of Typescript but 60% want to use it in the future.
Ts seems awesome but it looked like kind of a pain with separate ts and js files, mandatory type definitions not being present for lots of dependencies, and back when I looked at it seeming pretty all or nothing. I like flow. The people that built ts are brilliant too though. Curious if anyone has a good comparison between flow and ts. I've heard ts has improved a lot lately.
> mandatory type definitions not being present for lots of dependencies
That is the biggest detriment to typescript in my book. I played around with it for a bit but finding accurate (and up to date!) type definitions for external dependencies was a huge pain.
The survey also comments "few developers have used CoffeeScript, and apparently almost nobody wants to learn it" and concludes with "Some technologies [...] proved to be on their way out (CoffeeScript)."
Hopefully DHH recognizes this and deprecates CS out of Rails.
Not surprising. If you've ever had to work with CoffeeScript in a large code base with multiple developers, it's . . . not ideal. I can't stand it, personally.
I take issue with that statement. Just anecdotal, but I think these days Typescript is much more "popular" than CoffeeScript
