In Grunt the examples and virtually all code are wrapped up in one big function. Gulp doesn’t require this, and I’m under the impression many prefer this. However Grunt has a huge standard library.
I like code that doesn’t leave the left margin for long because it’s easier for me to see chunks of code. It also allows me to interleave code, which sometimes makes a lot of sense.
Using OOP, Grunt can be made to have this style. I took the Gruntfile for jquery and made it stay to the left margin while working the same way.
I won’t be sending a pull request, but I may do this on one of my own projects.
