High upon a rock, poised like a bird for flight, stark naked, his satin skin shining like gold and silver in the rising sun, stood a youth, tall, slim of body, not fully developed but with muscles promising, in their faultless, gently swelling outline, strength and suppleness to an unusual degree. Gazing down into the pool formed by an eddy of the river twenty feet below him, he stood as if calculating the distance, his profile turned toward the man who had just emerged from the bushes and was standing on the sandy strand of the river, paddle in hand, looking up at him with an expression of wonder and delight in his eyes.

A practical and concise introduction to CoffeeScript, a programming language that compiles into JavaScript and that makes working with JavaScript easier. The book lays out the basics of the language, its syntax, and the interesting features that set it apart from JavaScript. It should satisfy anyone with an intermediate level of understanding of JavaScript who needs a conceptual and practical introduction to CoffeeScript. The book is based around a practical project, leading you through the building of a simple HTML-based 2D game, and explaining the language's philosophy, syntax, and features step-by-step along the way. You'll be able to see results on-screen from the very beginning, starting with a simple JavaScript drawing function transformed into CoffeeScript. The game's code is based on well- understood principles and prior art, using common, simple programming patterns that are easy to grasp while also demonstrating CoffeeScript's expressiveness. This is a fun and fast-paced book that rewards you for each completed step with interesting game features. You will finish the book with the sense of accomplishment that comes from building something fun, as well as having gained a solid understanding of CoffeeScript and an interest in exploring its more advanced features.
