Not using 'any' is also perfectly fine, as you can with Javascript, Python, Ruby, etc.. And I guess that most companies just don't understand how I use Coffeescript.

Besides, I am not against others using Typescript, it's a fun experiment and a great opportunity for front-end developers to learn about static typing, enjoy it if you can! For me it unfortunately doesn't work, I've never gained from it because I generally don't have type issues. It's a pain in the ass that's constantly bugging me, pulling me out of the flow. It's a monster of a tool that tries to solve a problem I don't have.
