1 About this book (ES2019 edition)

1.1 What’s in this book?

This book makes JavaScript less challenging to learn for newcomers, by offering a modern view that is as consistent as possible.

Highlights:

• Get started quickly, by initially focusing on modern features.
• Test-driven exercises and quizzes available for most chapters.
• Covers all essential features of JavaScript, up to and including ES2019.
• Optional advanced sections let you dig deeper.

No prior knowledge of JavaScript is required, but you should know how to program.

1.2 What is not covered by this book?

• Some advanced language features are not explained, but references to appropriate material are provided. For example, to my other JavaScript books at ExploringJS.com, which are free to read online.
• This book deliberately focuses on the language. Browser-only features etc. are not described.
