Web Development & Design Foundations with HTML5

Chapter 14 Overview of JavaScript & jQuery

Using JavaScript, you can incorporate techniques and effects that will make your web pages come alive! JavaScript is an object-based scripting language used to manipulate objects associated with web page documents. For example, you can display an alert box containing an important message for the user, you can check the information that was entered into a form, and much more. jQuery is a JavaScript library that provides an easier way to code interactive effects with JavaScript. This chapter introduces JavaScript and jQuery while providing some examples that you can build on to create your own web pages.
