There is a line from Lion King where little Simba comments on his Uncle Scar's weirdness. Scar replies "You have no idea." The main point of this review is that Javascript is a really weird contraption, and that this book points this out in a way that is very helpful for programmers coming from more traditional compiled programming languages. I have programmed in C, C++, Java, C# for many years. I have read other books on Javascript which tried to teach by examples. With normal programming languages, this works fine. However, within a few hours with this book I realized that to understand Javascript, you must give up on some basic expectations you may have as a code developer. This was a surprise to me, but crucial to be able to learn Javascript well enough to work on non-trivial projects with existing code. Javascript is simply bizarre. There are many different ways to implement object-oriented patterns which all use different-looking code, and have subtle differences, making it so easy to get bitten by unintended consequences. From this book I learned that there is no one solid way to implement the basic pattern of your code, you must make a choice. If you try to read a Javascript book which teaches by examples, you will be in trouble when you actually start to modify someone else's Javascript code which used a different pattern. This book doesn't just show trivial examples, it methodically goes through how it works in enough detail so you can understand how it is working under the hood. Also, the text has plenty of warnings about buggy implementations and common pitfalls.
