Exploring JavaScript
ES2025 Edition
About the book
“Exploring JavaScript” makes the language 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.
- Optional advanced sections let you dig deeper.
- Complementary material: test-driven exercises and flashcards
- Covers all essential features of JavaScript, up to and including ES2025.
No prior knowledge of JavaScript is required, but you should know how to program.
In case you were wondering: This book was previously called “JavaScript for impatient programmers”. The new name reflects its rather large scope – which has exceeded initial plans for a long time.
