There's definitely improvements to the language in CoffeeScript. It makes sense; it was able to take 10 years of js experience and write a new language. But that doesn't mean CoffeeScript itself is without problems, or that it even improves development time. There's certainly many different ways to do things in CoffeeScript, like even calling functions (parenthesis is optional). Talk about having to think about syntax! http://stackoverflow.com/questions/12077114/coffeescript-syntax-structure-is-wrong http://stackoverflow.com/questions/12077114/coffeescript-syn... There are other ambiguities too due to the arrow pattern for defining functions. You have to be careful where you place stuff. CoffeeScript is definitely an improvement in some ways, but please don't market it as superior to javascript (I certainly prefer brackets). It's just different. All of this really doesn't make much difference in how long it takes you to ship products.
