Dan Tello covers all the important areas about these tools in this post. I love the way he breaks up the Gulpfile but the post is full of great tips and tricks.

I’ve always found require.js require statements to be ugly and internally caused me to not want to use it. It’s funny how the appearance of code can you give you a certain reaction without even using it.
