Learning JavaScript, 3rd Edition

JavaScript: The Definitive Guide, 3rd Edition is a JavaScript learning resource written by American technical author Ethan Brown and published in translation by People's Posts and Telecommunications Press. The book comprises 22 chapters and uses ES6 (ECMAScript 2015) as its language baseline, systematically outlining the framework of modern JavaScript knowledge: beginning with a first application and commonly used development tools, it progresses layer by layer through literals, variables, constants, and data types; control flow; expressions and operators; functions and scope; arrays and array processing; objects and object-oriented programming; Maps and Sets; exceptions and error handling; iterators and generators; functional abstractions; asynchronous programming; dates, times, and mathematical operations; regular expressions; JavaScript in the browser; jQuery; and Node.js. The content advances from elementary to advanced topics, accommodating beginners who need to build a foundation in the language while also covering advanced subjects such as asynchrony, generators, and regular expressions. It includes practical introductions to toolchains (version control and package management) that help readers apply their language knowledge to real front-end and back-end projects. The author has long worked in Web and Web service architecture, and his exposition leans toward engineering practice and conceptual explanation. The book is suitable as a long-term reference for readers who already have a basic grasp of syntax and wish to systematically fill out their modern JavaScript technology stack.
