Fun with Functional JavaScript

on YouTube ↗39m

" summary

Claim: JavaScript is practical for functional programming and the talk proves it by reimplementing an array normalization task three ways and running each demo successfully. Builds: vanilla JS map+flip+curry+compose to collapse ten lines into one; then uses lodash partialRight and built-in curry/compose to simplify further; finally uses FunctionalJS curried by default so map takes the function first. Also demos ES6 improvements like arrow + spread/rest (tail calls not yet available in engines). Results match and are more concise and readable.
