I've switched over to CoffeeScript for all projects where I get to choose. It's an all around better language than js if you tend towards the functional side. Iteration/comprehensions work like they should[1], destructuring simplifies extraction, there's a prototype binding construct in the language, less line noise, and everything is an expression. I also happen to like indent-significant languages and think it's a great DSL language. I could certainly produce the same code writing in JS, but what would the advantage be? I'm already doing a build step for combo/minification and if not, a --watch compile gives roughly the same workflow as raw JS. I have to search for a snippet of text rather than going to a line number when I'm debugging, but I think the coding gains/cleanliness is worth the slightly increased debugging effort. [1] With one gripe, `y = x + 1 for x in 0...10` got changed in August to match up with `z = x if x % 2` and friends (it was special cased) so y is now 10 instead of the array 1..10 and you have to wrap the comprehension in parens.
