If you are a curious JavaScript developer, interested simultaneously in tweaking the efficiency of your code, improving the conciseness of your code, and maintaining the readability of your code, this is the book for you. Ideally, the book is intended for readers working on JavaScript projects already, using frameworks such as jQuery and Backbone. Even if you’re already using Lo-Dash, this book will show you how to use it efficiently. While extensive JavaScript experience isn’t a requirement for this book, you should have at least some prior programming experience, in order to best understand the concepts presented.
