The bottleneck is never the time it takes to type the code.
Honestly, CoffeeScript is neat but it's not much of an improvement over JS. It's just as ugly and unreadable. It's only an improvement if you're counting characters.
I don't find CoffeeScript any less ugly or readable than JS. It seems incredibly redundent.
I'm sorry but what? Are python and ruby ugly and unreadable? Are they on the same level as js? Because coffeescript syntax is essentially a combination of the best aspects of both with a cleaner lambda syntax. I'd love to hear which languages you find beautiful and readable if cs doesn't meet your standards.
It's not about the time it takes to type code. Code that requires less typing is more succinct and therefore easier to read and understand.
You don't find it easier to read. Fair enough. I think a lot of people do. I personally found it much easier to write structured code in Coffeescript than in Javascript straight.
