"《Learning Underscore.js》是一本面向JavaScript开发者，特别是希望扩展其功能性编程技能的开发者编写的教程书籍。作者采用实例驱动的方式，引导读者理解并掌握Underscore.js库，这是一款流行的现代JavaScript函数式编程库。本书适合基础知识扎实的开发者，无论他们偏向于 Imperative、Object-Oriented、Functional或其他编程风格，都可以利用Underscore.js来构建高效且可持续的JavaScript应用。在学习过程中，读者将逐步了解Underscore.js的核心概念，如如何通过现代JavaScript开发工作流引用和调用其内置函数。书中重点讲解了如何运用Underscore.js处理JavaScript数组、对象和函数，同时探讨了对象导向和函数式编程技术的应用。此外，书中的章节涵盖如何在客户端、服务器端和数据库环境中利用Underscore.js，以及如何将其与其他相关库结合，提升代码的复用性。作者还会指导读者如何在不同环境间重用Underscore.js代码，并为即将到来的ECMAScript 6标准和兼容旧浏览器做好准备。全书采用实践导向的方法，每个章节都配以深入的示例和详尽的解释，帮助读者充分理解和掌握Underscore.js API。《Learning Underscore.js》不仅提供了实用的技术指导，还强调了轻量级和高效的开发流程，有助于读者构建健壮的JavaScript应用程序。无论你是初学者还是有一定经验的开发者，本书都能帮助你在功能性编程领域迈出坚实的一步。"

Preface

[ vii ]

Chapter 6, Related Underscore.js Libraries and ECMAScript Standards, discusses

advanced topics such as the link between Underscore and JavaScript standards,

libraries that augment or can even replace Underscore, with a focus on taking

advantage of the new ECMAScript 2015 (ES6) features.

Chapter 7, Underscore.js Build Automation and Code Reusability, introduces a build

automation solution together with strategies to reuse Underscore based code

between different application hosts.

What you need for this book

You need to have the Node.js runtime installed and it is available at

https://nodejs.org/. Details on how to install it can be found in

Chapter 1, Getting Started with Underscore.js.

All the code in this book can be edited in any text editor or IDE that you are

familiar with and has support for the JavaScript language.

Who this book is for

This book is for developers with fundamental JavaScript knowledge who want to

use modern JavaScript libraries to advance their programming skills. Underscore is

one of the most important libraries you should be familiar with and the book will

help you achieve this goal by going through its fundamentals and using it in a wide

variety of contexts. This book should be relevant to anyone who:

• Is interested in building web applications, single-page web applications

or JavaScript-based desktop, mobile, or embedded applications

• Wants to use Node.js to build web applications or web services

• Wants to work with databases such as MongoDB or PostgreSQL and

leverage their JavaScript support

Conventions

In this book, you will nd a number of text styles that distinguish between different

kinds of information. Here are some examples of these styles and an explanation of

their meaning.

Code words in text, database table names, folder names, lenames, le extensions,

pathnames, dummy URLs, user input, and Twitter handles are shown as follows:

"We just need to open the SpecRunner.html le in a browser and we should see

this output."
