You Don't Know JS Yet: Get Started

Get to know JS

About the Book

The worldwide best selling You Don't Know JS book series is back for a 2nd edition: You Don't Know JS Yet. All 6 books are brand new, rewritten to cover all sides of JS for 2020 and beyond. You'll still get in-depth coverage of the core language, applied in useful code organization patterns for your programs. And of course, through Kyle's unique perspective and conversational tone, explore passionate, reasoned debate of the most common questions developers face.

Get Started, the first book in the new edition series, is where to start your journey of knowing JS more deeply. This book surveys the language in multiple layers of detail, laying out a roadmap with the other books as guides for your learning and growth. For any developer hoping to move from early JS experience to a deeper level, here is your first step to get started.

In Get Started, you'll explore:

  • How the JS language evolves, how JS programs actually work, and busting of common myths
  • The building blocks of JS: values, functions, and more
  • The roots and pillars of JS: types, closure, and prototypes
