Introducing Functional Programming with Underscore.js
Michael Fogus
简介
While some web developers dismiss JavaScript as a flawed language, this succinct book shows you how to make the best of it by practicing a functional style of JavaScript programming. Written by Michael Fogus - a core contributor to Clojure and ClojureScript, and author of The Joy of Clojure (Manning) - this book is packed with not only the how of functional programming, but also the why. Each topic illustrated with pointed examples. You'll also get a thorough reference to the Underscore.js library and its idioms, including: Closures Applicative programming Laziness Immutability Higher-order functions Purity Combinators Currying and partial application
