I have always been disappointed in my experience with IDEs and JavaScript integration and would be glad to know what people use for JavaScript (I'm actually asking the question to everyone).
I'm attracted to the idea of a shorter function syntax not only because it reduces the number of characters of the "function" keyword, but also because it gets rid of the "return" keyword (and corresponding semicolon). The particular case where I would enjoy shorter syntax is when using inlined functions in array extras. ---- // assuming a is an array a.filter( (e)->(typeof e === "number" && e>3) ) .map( (e)->(e*e) ) .reduce( (prev, curr)->(prev+curr), 0); ---- This is obviously extremely subjective, I admit. And there is no right or wrong answer/opinion, it's really a matter of taste. I actually prefer the idea of the # notation, because it looks "more" like a function with its brackets ("{" and "}") while in my example, without any help of syntax highlighting, the reader can easily get lost in nested parenthesis. Same example with #: ---- // assuming a is an array a.filter( #(e){typeof e === "number" && e>3} ) .map( #(e){e*e} ) .reduce( #(prev, curr){prev+curr}, 0); ---- This looks more clear to me. But once again, this is very subjective. Your message seems to assume that the choice of providing a shorter syntax is to help JS code writer. I have the opposite opinion: a shorter syntax should be introduced to help code readers. In most cases I have seen for array extras functions, the function has only one return statement. While reading the code, having the function inlined avoids to look for the function in some other place in the code and getting rid of a dozen character makes the line shorter without introducing ambiguity.
