I still use it daily since I find it so much easier to write and read than having my code littered with semicolons and braces, and it enforces correct whitespace. I do see its limitations, and I wish efforts to marry Coffeescript with Typescript would be more serious.
It's really not. Coffeescript might be nice with fresh development and a small codebase but it's really bad when you're trying to figure out someone else's code.
