To each their own. Personally I dislike nested function calls in general and would use intermediate variables with descriptive names. var calculatedOne = andthisCalculatedOne(anArgumentThatMeansSomething, anotherWordyName); myFunctionThatDoesStuff(someArgument, calculatedOne); Edit: That "anotherWordyName" is supposed to be column justified, HN really needs <code> tags instead of this indentation nonsense. The extra vertical space is easily worth the increase in readability IMO. I've never touched proportional formatted code beyond a day or two when I was forced to by my environment, and all I encountered was more annoyances in getting my code to align properly. I'm glad you found some benefit, but I'd argue those benefits could be achieved any number of other ways.
