Explore the inner workings of the world's most popular programming language and enjoy the power and control that comes only from deep knowledge! In JavaScript in Depth, JavaScript and Node legend James M. Snell goes beyond the basic syntax and common implementations to expose the secrets of its engines, runtimes, and language design decisions.
In JavaScript in Depth, you will learn how to
Take advantage of the internals of the JavaScript language
Understand how runtimes like Node.js, Deno, and Bun differ
Discover how features like streams, file systems, and crypto APIs really work
Avoid common performance traps and subtle bugs
Written by core Node.js and TC-39 committee contributor James M. Snell, JavaScript in Depth teaches you what's really happening when JavaScript handles asynchronous tasks, manages memory, or interacts with system APIs. This interesting and entertaining book is filled with insights that you reason better about your code, your tools, and your runtime environments.
about the book
JavaScript in Depth isn't a "how-to" guide-it's a "how it works" guide. In it, you'll find detailed code samples, in-depth technical breakdowns, and real examples drawn from production environments, all connecting JS theory to everyday development. You'll see how JS engines execute code and interact with system APIs, how runtimes power your applications, and why JavaScript behaves the way it does. Whether you read it cover-to-cover or dip in as an easy reference, this book will help you refresh obscure topics, troubleshoot complex bugs, and make best use of AI-generated code snippets.
