    Book Description

    If you are a curious JavaScript developer interested simultaneously in tweaking the efficiency of your code, as well as improving the conciseness of it, and maintaining the readability of it, then this is the book for you. Ideally, the book is intended for readers already working on JavaScript projects and 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, you should have at least some prior programming experience in order to best understand the concepts presented.

    What you will learn

    • Analyze the difference between arrays, collections, and objects and look at how LoDash treats them
    • Understand the subtle differences between iterating over arrays and objects, along with objectcreation patterns used with LoDash
    • Exploit and work with LoDash functional tools, such as partially applying arguments, and composing higherorder functions
    • Explore the various approaches of MapReduce and their relationships with other LoDash functions
    • Build your own LoDash application for various environments
    • Compare LoDash with other libraries and decide where LoDash is a good fit
    • Understand the key LoDash design principles and utilize this knowledge to deliver performant user interfaces
