Secrets of the JavaScript Ninja, Second Edition

Secrets of the JavaScript Ninja, Second Edition is an advanced JavaScript guide co-authored by John Resig, creator of jQuery, together with Bear Bibeault and Josip Maras. The Simplified Chinese edition was published by Posts & Telecom Press in 2018; it runs 429 pages and about 605,000 characters. Unlike introductory books that catalog syntax and APIs, this one focuses on the parts of JavaScript most easily skipped over yet decisive for code quality: functions, scope and closures, prototypes and objects, collections, regular expressions, modularity, and on the browser side the DOM, events, and cross-browser compatibility. The book has four parts: Warm-up, Understanding Functions, Digging into Objects, and Knowing the Browser. Part One lays out the basic groundwork—JavaScript's evolution, the browser runtime and page-building process, and debugging and testing. Part Two devotes four chapters to functions, moving from definitions and arguments and invocation patterns to closures and scope, then to generators and promises. Part Three covers object-oriented programming and prototypes, controlling property access, arrays and Map/Set, regular expressions, and code modularization. Part Four returns to the browser, covering DOM manipulation, the event mechanism, and cross-browser development techniques. The book incorporates new features from ECMAScript 6 and 7 and includes end-of-section exercises with an answer appendix, so readers can write and verify code as they read.
