I spoke about the different Javascript Build systems at KCDC. I wanted to make sure my slides are available to any who wanted to view them.
A few things about the slides:
There is a Gruntfile.js that contains tasks that I talked about in the presentation. There is also a gulpfile.js that does the same tasks as the Gruntfile. It will show you the differences between the two systems.
The slides are found here, and the repo for the files here.
I hope this is helpful for some out there, Enjoy!
