Sure, you have a few extra newlines and semicolons, but the minifier will remove them anyway so no harm.

This semi-colon is added to prevent changing the code behaviour (the famous line ending with parentheses, etc) Most people will use a JS minifier If they don't, a single extra character is unlikely to change much If I'm right about all the above: Why don't we simply always add a semi-colon regardless of what the file ends with?
