The Javascript Handbook

The JavaScript Handbook

The JavaScript Handbook follows the 80/20 rule: learn in 20% of the time the 80% of a topic. I find this approach gives a well-rounded overview. This book does not try to cover everything under the sun related to JavaScript, just the fundamentals. You can reach me on Twitter @flaviocopes. I hope the contents of this book will help you achieve what you want: learn the basics of JavaScript. This book is written by Flavio Copes. I publish web development tutorials every day on my website https://flaviocopes.com. Enjoy!
