We know the functional programming (FP) hype train's been riding strong the past few years, especially in the JavaScript community. We extol FP in countless books, videos, and blog posts, with no sign of slowing down. As a result this course isn't to convince you, today's JS developer, of how awesome FP is. I'm simply sharing some popular patterns using Ramda, an FP library that I've blogged on many times. Before going through them, though, we will lay the groundwork with concepts like pure functions, currying, and point-free style. You're already doing FP through map, filter, reduce, and Lodash, so why not dive a bit deeper and see if you like it down here?
