Going Functional with JS

on YouTube ↗49m

" summary

Claims that JavaScript can be used functionally, demonstrates it with Ramda and ES6 generators, and shows live code that maps [10,20,30,40] to [11,21,31,41], reduces to 100, composes to 25 and transduces purchases to 46. Covers currying, compose/pipe, lenses, Maybe monad and the Fantasy Land spec, notes laziness via a generator to yield 0..billion but only compute 0..5, and says examples run as expected while pointing out library tradeoffs versus purely functional languages.
