Simplifying JavaScript. J. Morgan

 This book is for anyone who has a little programming experience. It helps to have some JavaScript experience, but that’s not strictly necessary. I’ll assume that you know some basic programming concepts, such as loops, conditionals, functions, and classes. In short, if you’ve seen modern JavaScript and you’re excited to learn more, then this book is for you.
 You may feel like you woke up in a strange new world. That’s not a bad thing. In fact, this new world is awesome—the coffee’s brewing, and the aroma of freshbaked danishes makes this new world a place you want to wake up to. JavaScript is better than ever—it’s time to enjoy it.
