Add This Book to Your Collection
You learn about object attributes such as [[Enumerable]] , [[Value]], [[Writable]], [[Configurable]] and what they do. The book goes over constructors, prototypes, and inheritance showing you how they all work. One of my favorite parts of the book is how hasOwnProperty is explained...now I get it! I do like how the book starts off going over types and how to property use typeof and instanceof.
