The problem is that it's giving me more files that are outside the .js extension and I'm wondering if the filemagic command has a property for javascript files or if there is a better way to construct the rule to capture only .js extension types.<br>

You should employ some additional file keywords (filemagic) in order to get just Java scripts. Some more info can be found here -<br>
