A Quick Word About Semicolons

JavaScript Has Semicolon Insertion

If you don't type a semicolons at the end of a line, JavaScript engines will do it for you. You can read about the rules here.

Usually, you don't need to type them, so I tend not to. This behavior annoys some people. Thats O.K., You can't please everybody.

Some of those annoyed people say it's safer to just always use semi-colons, but as @mpj points out, semicolons will not save you.
