Today, JavaScript is used on most of the pages of a modern website, from small individual sites to the largest commercial sites. And wherever JavaScript is used, you’ll often find jQuery, a classic JavaScript library. That’s why every web developer should know how to use JavaScript for what it does best and jQuery for what it does best. Now, this one book will help you master all of the JavaScript and jQuery skills that every web developer should have.

What this book does

To present the JavaScript and jQuery skills that you need in a manageable progression, this book is divided into four sections. These sections represent the levels of expertise that you’ll develop with this book.

Section 1: JavaScript essentials

Section 1 presents a 7-chapter course in JavaScript that gets you off to a great start. This section works for programming novices as well as experienced programmers because it lets you set your own pace. Once you finish it, you’ll be able to develop, test, and debug JavaScript applications. And you’ll have a solid set of skills for getting the most from jQuery.

Section 2: jQuery essentials

Once you know the JavaScript essentials, the 4 chapters in section 2 present the jQuery skills that you’re most likely to use. The first chapter in this section presents the core jQuery skills. Then, the next 3 chapters focus on effects and animations, forms and data validation, jQuery plugins, and jQuery UI widgets.

Section 3: Advanced JavaScript skills

After you finish sections 1 and 2, you’ll have the basic JavaScript and jQuery skills that every web developer should have. Then, the 5 chapters in section 3 will build out your skills, so you can handle more demanding tasks. Here, then, you’ll learn more about how to use numbers, strings, and dates...how to handle exceptions and use regular expressions...when and how to use browser objects, cookies, and web storage…how to work with arrays and maps...and how to create and use your own objects.

Section 4: Take it to the next level

The 3 chapters in section 4 will raise your JavaScript skills to a new level of expertise. Here, you’ll learn more about working with closures, the module pattern, and ES modules so you can safely share your code with other programmers. You’ll learn how to use Ajax with the Fetch API and Promise objects to asynchronously update a web page with data from a web server. And you’ll get introduced to doing server-side scripting in JavaScript by using Node.js.

Why you'll learn faster and better with this book

Like all our books, this one has features that you won’t find in competing books. That’s why we believe you’ll learn faster and better with our book than with any other. Here are a few of those features:

  • This book is designed to teach you the skills you’re going to need on the job without wasting your time on skills that you aren’t likely to need. That sounds simple, but most JavaScript and jQuery books either overwhelm you with information that you’ll never use or trivialize the subject by avoiding all of the complications. In contrast, this book presents even the most complex features in a manageable way, to give you the skills and confidence you need to work on your own.
  • If you page through this book, you’ll see that all of the information is presented in “paired pages,” with the essential syntax, guidelines, and examples on the right page and the perspective and extra explanation on the left page. This helps you learn faster by reading less...and this is the ideal reference format when you need to refresh your memory about how to do something.
  • To show you how JavaScript and jQuery work, this book presents dozens of complete applications that range from the simple to the complex. We believe that studying the code for complete applications is critical to the learning process... and yet you won’t find programs like ours in other JavaScript and jQuery books.
  • Of course, this book also presents dozens of short examples, so it’s easy to find an example that shows you how to do what you want to do. Even better, our paired pages make it much easier to find the examples that you’re looking for than it is with traditional books in which the examples are embedded in the text.
  • Like all our books, this one has exercises at the end of each chapter that give you hands-on experience by letting you practice what you’ve learned. These exercises also encourage you to experiment and to apply what you’ve learned in new ways…just as you’ll have to do on the job.

What's NEW in this edition

  • All chapters have been thoroughly updated to use modern ECMAScript and today’s best coding practices. For example, you’ll find:
    • Use of the let and const keywords instead of the var keyword wherever that improves the code
    • Use of arrow functions instead of function expressions for more concise code that also gets rid of the confusing and error-prone this keyword
  • New coverage of the popular Visual Studio Code text editor
  • New coverage of sets and maps
  • New coverage of using classes to create JavaScript objects
  • New coverage of ES modules
  • A new chapter on using Ajax with the Fetch API and Promise objects
  • A new chapter that shows how Node.js allows you to use JavaScript for server-side scripting

Who this book is for

This book is for anyone who needs to know how to develop JavaScript applications and benefit from jQuery. Today, that includes all web developers who are in either of these groups:

  • Web designers who use HTML and CSS and would like to know how to enhance their web pages with JavaScript…no previous programming experience required
  • Server-side programmers who use languages like Python, PHP, JSP, or ASP.NET and would like to use JavaScript to provide client-side scripting for their web applications

What software you need

To develop JavaScript applications, you need:

  • A text editor: This book recommends Visual Studio Code because it’s free and provides many excellent features for developing JavaScript applications.
  • A modern web browser: This book recommends Google Chrome because it provides excellent developer tools for debugging JavaScript applications.

To help you install these products, Appendix A provides the procedures that you’ll need for Windows, and Appendix B provides the macOS procedures. In addition, chapter 1 presents a short tutorial on using Visual Studio Code, and chapter 5 shows you how to use Chrome for debugging.

The perfect companion book

Murach’s HTML5 and CSS3 (4th Edition)

Murach’s HTML5 and CSS3 is the perfect companion to our JavaScript and jQuery book because it shows how to build web pages with HTML5 and CSS3. When you combine this book with our JavaScript and jQuery book, you’ll have a complete reference set for building web pages.

What people said about the first edition

“If you are new to web design or an old pro like me, this book is a must-have in my opinion. I love how it starts out with the basics and then moves on to the good stuff. Each chapter is full of examples and sample code showing you how to do the most common techniques that you will face as a web developer/designer.
     “I have not seen a better book on the subject. This one will be on my desk for a while!”
- Web Developer, Colorado

“I just finished a pretty heavy application project, the first serious work I have done with jQuery and Ajax. Along the way, I had to deal with preloading images, manipulations of the DOM, tabs, plugins, and Dialogs…. I kept this book at my side throughout the entire project, and it was indispensable. The answers were right there at every turn. All the examples made sense to me, and they all worked!”
- Alan Vogt, ETL Consultant, Information Builders, Inc.

“What I like about this and other Murach books is that within minutes of opening the book, you are developing hands-on with the technology in question.”
- Charles Zimmerman, Developer

“An essential characteristic of this book, as well as the other Murach books, is that the examples, programs, and applications are all thoroughly tested. This book will work WONDERFULLY to help you build better and more robust websites!”
- Marvin Schneider, Instructor, New York

“I have several books on JavaScript, but the best one is this one. The text, examples, descriptions, and even the layout all bring you, the learner, an ease of use that is missing in other books.”
- Chris Wallace, Denver Visual Studio User Group
