Advanced jаvascript: Patterns, Performance, and the Tools of Professional Developers (Practical Programming) by Jacob Ren English | June 28, 2026 | ASIN: B0H6TYD48B | 149 pages | EPUB | 0.17 Mb This is the book that makes the language make sense.
Most jаvascript developers know how to use the language. Fewer understand how it actually works - what the engine does, why closures behave the way they do, what the event loop is really doing, and why the code they wrote is slow. Advanced jаvascript is for the developer who wants to close that gap for good. This book doesn't just teach you more syntax. It teaches you how to think like a senior developer - in patterns, tradeoffs, and systems. What's inside: Under the hood: The V8 engine, the call stack, execution contexts, the scope chain, and how the event loop actually processes microtasks and macrotasks - with clear, practical implications for your code Advanced OOP: Prototypal inheritance, the class keyword decoded, private fields, Proxy and Reflect, generators, Symbols, and iterators Functional programming: Currying, memoization, the Maybe pattern, function composition, and recursion with trampolining Async mastery: AbortController, Web Workers for true parallelism, building an event emitter from scratch, debounce and throttle implemented properly Design patterns: Factory, Builder, Observer, Strategy, State Machine, Decorator, and Facade - with real, production-grade jаvascript examples Performance: Profiling with DevTools flame charts, avoiding memory leaks, DOM batching, lazy loading with dynamic import, and Intersection Observer Modern tooling: TypeScript fundamentals, unit testing with Jest, Node.js file system and HTTP servers Capstone: Build a reactive state management system from scratch (think mini-Redux), plus security, the jаvascript ecosystem map, and senior developer thinking patterns This book is for you if: You've been writing jаvascript for a while and want to understand it at a deeper level You're preparing for senior developer roles or technical interviews You want to understand how frameworks like React and Redux actually work under the hood Every concept is grounded in real use cases. Nothing is academic for the sake of it. If it's in this book, it's because you'll encounter it in production code.
