Content for the ebook "Understanding ECMAScript 6"
by Nicholas C. Zakas
ECMAScript 6 represents the biggest change to the core of JavaScript in the history of the language. Not only does the sixth edition add new object types, but also new syntax and exciting new capabilities. The result of years of study and debate, ECMAScript 6 reached feature complete status in 2014. While it will take a bit of time before all JavaScript environments support ECMAScript 6, it's still useful to understand what's coming and which features are available already.
This book is a guide for the transition between ECMAScript 5 and 6. It is not specific to any JavaScript environment, so it is equally useful to web developers as it is Node.js developers.

Roughly every week or two the changes in GitHub are published to Leanpub.
Everything in GitHub is a work in progress. Those parts that are known to be correct and fully-formed enough to be valuable are published to Leanpub. That's why there's more content in GitHub than is available on Leanpub, as GitHub contains everything, including content that's not quite ready for the book.
The topics covered, and the order in which those topics are covered, are exactly the same between the print and Leanpub versions. The only real differences are in some words and phrases that have been altered by the copyeditors either for clarity or to follow No Starch's style guide. These changes are not backported into Leanpub because they happen on PDFs and sometimes opaquely, making it difficult to keep the two versions in sync.
