I remember having a bug once in (I think) IE8 where I had a comma after the last element an an array (like the 'greatarray' shown in this article.<p>The browser didn't accept a comma after the last element in an array and IIRC the compiler breaks so badly that it puts the reported error at line 1 character 1, possibly for a different file entirely.<p>Spent a LONG time on that.<p>I kind of reject his assertion that JavaScript without semi colons is "better code"<p>The logic, flow, maintainability, understandability, performance and, actually doing the right thing all make for better code.<p>Semicolons? Not so much.
