There are advantages and disadvantages of course. Some people find it hard to maintain a large list of variables at the beginning of each function. It also leads to unnecessary comments, for when the variable gets far away from its point of usage you need to "introduce" it to the reader beforehand. Once you understood scope it's not that essential where you put your variable declarations. Even if you made a mistake I find it very easy to spot these kind of situations. I agree with Garrett that it's more like a style preference. Write code that looks unambiguous for you and others reading your code. Nothing else matters. - Balázs -- To view archived discussions from the original JSMentors Mailman list: http://www.mail-archive.com/[email protected]/ To search via a non-Google archive, visit here: http://www.mail-archive.com/[email protected]/ To unsubscribe from this group, send email to [email protected]
