About the Bundle
A series of 5 books that will guide you to JavaScript mastery. These books are in progress, as follows:
Currently, the page count for all books is about 1701 pages. By the time all the books are complete, the total page count should be between 2200 and 2600 pages.
About the Books
This book is based on a tried and tested learning methodology.
This learning methodology will give you the best possible results in the shortest amount of time!
Along the way, you'll learn how to build truly useful apps in JavaScript, which will speed up your workflow and help you with your daily tasks.
This book is a second in the series of 5 books on JavaScript.
In Book 1 we learned a lot about JavaScript. In Book 2, we "backfill" the wholes in our knowledge by having a detailed, in-depth look at all the built-in objects in JavaScript.
Understanding all the available methods and properties on built-in objects will do wonders for our confidence as JS developers.
Once you read this book, you can rest assured that whatever JS code comes your way, you'll know where it's coming from and how it works.
Books 1 and 2 are a solid foundation for working with some real-life code, with a lot of code snippets, and specific use cases. This is what Book 3 is about.
However, at the end of Book 2, we'll have a large section with all the code snippets extracted from both Books 1 and 2 (currently at about 90 code snippets, but as this book gets updated, by the end it should have at least 300 code snippets).
Both Books 1 and 2 aim to "draw the map of JavaScript", and are indeed a Better Way to Learn JS, because they are like a story about JavaScript that unwinds right before you.

This book is the third in my 5-book series on JavaScript.
In Book 1 we learned about JS basics, and we got a nice foundation in the language.
In Book 2, we covered all the built-in objects in depth.
However, there is something lacking from both books: some more practical, simple examples, gotchas, tips and tricks.
This is what Book 3 is aiming at. We will go through various examples dealing with randomness, strings, numbers, DOM manipulation, and so on, all in the format of simple exercises, down-to-earth examples, with a lot of additional explanation so that the examples really make sense.
Currently, there are about 70 separate useful snippets. But this book is still in progress. By the time it's finished, there are going to be at least 300 snippets in this book.
If we take into account the first two books, by the time all three books are finished, we will be close to about 900 exercises to master your JavaScript knowledge.
My goal is to make a very comprehensive overview of the JavaScript language, spread over these 5 in-depth books, rich with examples and exercises.

This book is the fourth in my 5-book series on JavaScript.
In Book 1, we learned about JS basics, with an in-depth coverage of foundations.
In Book 2, we examined all the built-in objects in depth, including their properties, methods, and constructors.
In Book 3, we went through a bunch of code snippets, simple "sub-programs" that dealt with a specific issue, such as emulating a pair of dice, or capitalizing each first letter in a sentence.
In this book, Building Mini Apps, we're continuing from simple snippets from Book 3, and we're using all the things we've learned so far to build some specific "mini apps": standalone solutions to various issues.
This is the fifth book in this 5-book book series.

We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.
(Yes, some authors have already earned much more than that on Leanpub.)
In fact, authors have earned over $15 million writing, publishing and selling on Leanpub.
