Don't let ready-made web building kits limit you. Use JavaScript to let your creativity flourish and turn your ideas into reality.

Just a few years ago, JQuery was undisputed leader in the field of DOM manipulation. In the meantime, however, JavaScript has caught up. Today, you can write highly concise and comprehensible code with pure JavaScript. In the past, programmers always had to take different browsers into account. Today's browsers speak a common modern JavaScript and offer standardized DOM.

An essential foundation

If you are looking to create large single-page applications using frameworks such as Angular or React, it is essential that you understand the underlying browsers' API. It will allow you to devise alternative solutions for when the frameworks reach their limit.

Modern syntax

This book uses the current ES6+/ES2017 syntax presented in Volume 1, enabling you to write very short, concise, and above all, well-readable code.
