JavaScript Allongé is a first and foremost, a book about programming with functions. It’s written in JavaScript, because JavaScript hits the perfect sweet spot of being both widely used, and of having proper first-class functions with lexical scope. If those terms seem unfamiliar, don’t worry: JavaScript Allongé takes great delight in explaining what they mean and why they matter.
JavaScript Allongé begins at the beginning, with values and expressions, and builds from there to discuss types, identity, functions, closures, scopes, collections, iterators, and many more subjects up to working with classes and instances.
It also provides recipes for using functions to write software that is simpler, cleaner, and less complicated than alternative approaches that are object-centric or code-centric. JavaScript idioms like function combinators and decorators leverage JavaScript’s power to make code easier to read, modify, debug and refactor.
JavaScript Allongé teaches you how to handle complex code, and it also teaches you how to simplify code without dumbing it down. As a result, JavaScript Allongé is a rich read releasing many of JavaScript’s subtleties, much like the Café Allongé beloved by coffee enthusiasts everywhere.
