JSMin with sourcemaps (grunt flavor)

Since this is a tool that creates an output format, I think it is expected that if you find it you have a general idea of what it does. I don't believe there is an onus on the developer to include information about a general topic the tool is for (if they did, they would need tdo include what grunt is, what jsmin is, what sourcemaps are, why they are good, blah blah blah)

That being said, sourcemaps are a new feature in web dev environments that allows you to debug the compressed javascript as though it is it original uncompressed file. It does this by taking a automatically generated file created by the javascript compressor that is referenced in the compiled javascript as a comment.
