Edit Question
Title
Body
It is valid JavaScript to write something like this: function example(x) { "Here is a short doc what I do."; // code of the function } The string actually does nothing. Is there any reason, why one shouldn't comment his/her functions in JavaScript in this way? Two points I could think of during wiriting the question: The string literal must be initiated, which could be costly in the long run The string literal will not be recognized as removable by JS minifiers Any other points? Edit: Why I brought up this topic: I found something like this on John Resig's Blog , where the new ECMA 5 standard uses a not assigned string literal to enable "strict mode". Now it was my interest to just evaluate, if there could be uses or dangers in doing such documentation.
