CoffeeScript Ristretto

An intense cup of code

About the Book

"I particularly enjoyed this small book because I've reached for it a hundred times before and come up empty-handed. Large and heavy manuals on object-oriented programming and JavaScript are all around us, but to find a book that tackles the fundamental features of functions and objects in a brief, strong gulp, is rare indeed."—Jeremy Ashkenas, creator of the CoffeeScript Language
"Loving CoffeeScript Ristretto!"—Larry Marburger
"I was also seriously caught up by [the] digression into espresso, ristretto, etc.Worth the purchase just for the intro."—Chris Smith
"Best explanation of closures i've seen yet."—Jerry Anning

CoffeeScript Ristretto is a book about programming with functions that uses the CoffeeScript programming language for the examples and exercises. CoffeeScript Ristretto is for:

  • Programmers learning CoffeeScript who want a thorough grounding in its fundamentals rather than a cursory treatment of its syntax.
  • Programmers already using CoffeeScript who want to go back and take a deep dive into programming with functions and combinators.
  • Any programmer curious about programming with functions.

CoffeeScript Ristretto's primary focus is functions as first-class values and advanced topics built on those fundamentals such as callbacks, combinators, method decorators, fluent APIs, and continuation-passing style. Download two free sample chapters and see for yourself!
