Link to the e-book on Gumroad —

The JavaScript Array methods are one of the most used methods in JavaScript. They get the job done in our projects, but they are elusive sometimes.

I decided to help out developers by compiling all the JavaScript Array methods in a book. This book is a go-to book by developers or a handbook. With this book you don’t have to scour around the internet for a comprehensive definition of any Array methods, all you have to do is open this book and you are way ahead of your peers/colleagues.

I made each method in a separate chapter so you can jump straight to what you want.
