JavaScript Objects Functions and Arrays Explained, 2nd Edition

Book Description

Shifting the emphasis of learning from memorizing to understanding JavaScript.

“If you are looking for a source that describes the most common methods from the JavaScript library, this is it. This is a great reference book.”

How many times have you attempted to learn JavaScript, only to put it on the side because it was too complex or you just felt overwhelmed by the information overload?

This may be the book that will propel you forward to become a JavaScript programmer. Get yourself ready and cross that bridge now, download the eBook.

JavaScript Objects Functions and Arrays Explained covers a lot of material as you may see from the index below. However, each chapter is self-contained and easy to understand with plenty of illustrations and links to files of code you can physically copy. The author is, above all, a teacher.

This is a method to learn and to refer back later. The author recommends to read and review the book several times. It is easy to grasp but powerful when repeated the second time around.
