Functional Programming in 5 Minutes

If you checked out my last post you’ll know that I have been doing lots of JavaScript coding as of late, both inside and out of Brackets. I have also been doing a series of performance tests (1, 2, 3) between popular jQuery methods and their native DOM equivalents.
