Is there a tool\ utility\website that I cna use to pass a JS file\JS Code Snippet and it detects all the browser dependant code ?

How do most programmers go about converting browser dependant JS code into browser independent code? I have a JS file i made a while back which only runs on IE and i wanna make it browser independent. Im planning on using ProtoType.JS. Is there any way to identify all the lines of code that need changing so then I can find the equivalent prototype.js fxns to replace them.
Or do I just have to go by line by line in debug mode ?

I know of no such tool, sorry. I guess that's a hard lesson in writing browser-independent code in the first place.

I'd not recommend a line-by-line translation. If you are going to be using Prototype, it'd be best to look at how you are doing things at a higher level and start doing things using Prototype's help even where you do not detect cross-browser issues. You are liable to find your code vastly simplified.
