http://jsbeautifier.org/ is helpful to indent your minified JS code.

Also, with Google Chrome you can use "pretty print". See the example screenshot below showing jquery.min.js from Stack Overflow nicely indented right from my browser :)

Answer 4

I think it could be almost any javascript error/typing error in your application. I tried to delete one file content after another and finally found the typing error.

I also got this error pointing to the end of the last script block on a page, only to realize the error was actually from clicking on an element with a onclick="pagename" instead of onclick="window.location='pagename'". It's not always a missing bracket!

I got this error when I was trying to write a javascript bookmarklet. I couldn't figure out what was causing it. But eventually I tried URL encoding the bookmarklet, via the following website: http://mrcoles.com/bookmarklet/ and then the error went away, so it must have been a problem with certain characters in the javascript code being interpreted as special URL control characters.
