Check javascript for missing ";" before compression

Question

I'm doing some optimizations and decided to compress my javascript files using YUI Compressor. The problem is, that some code lines are missing ";" at the end, since javascript allows that and developers do not look too much at this.

Is it going to be a problem when code is compressed? If it is, is there a way to check javascript for lines that are missing ";"?

Answer 1

jsLint can check your code for that. And yes it will most likely cause issues unless the compressor actually contains a JavaScript parser and actively fixes missing semicolons.

Answer 2

According to this SO answer, YUI Compressor can handle it.
