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.
