Enhancing User Experience: Missing chapter of my book `Unlocked JavaScript`

My book “Unlocked JavaScript” (www.packtpub.com/web-development/javascript-unlocked) has been released on December 7, 2015.

This book is for developers already familiar with JavaScript who want to level up to get the most out of the language. The book is practice–oriented and would be most helpful for those who is used to `learn by doing` as the topics are thoroughly covered with real-life examples and tutorials. This is an extract of a chapter not included in the book.

As you likely know, in addition to new syntax, HTML5 introduces powerful features and APIS that can be used with JavaScript. Some of them such as Web Storage, IndexDB, FileSystem, Workers, Custom Elements, HTML Imports, Shadow DOM and Templates we examine in the book. Here I want to share with you a few HTML5 API that you may not be even aware of. Nonetheless they may help you to improve UX in your web application significantly.
