Grunt doesn't do dirty-file dependency checking. Gulp does, sort of, but it's awkward.

There are many, many build tools in JS-land. Grunt and Gulp happen to be the most popular. (This isn't really due to technical merit. They're popular mostly because they're popular.) My personal favorite is Jake, which is a classic Rake-like (or Make-like) tool.

Or instead of a Make-like tool you could just use Make itself :) Works really well.

You could, but I much prefer more expressive tools. Make's DSL is spectacularly crappy.
