The JavaScript Specialist course focuses on the fundamental concepts of the JavaScript language. This course will empower you with the skills to design client-side, platform-independent solutions that greatly increase the value of your Web site by providing interactivity and interest. You will learn how to use JavaScript to communicate with users, modify the Document Object Model (DOM), control program flow, validate forms, animate images, create cookies, change HTML on the fly, and communicate with databases.

The first part of this course focuses on essential JavaScript principles and techniques, including common programming practices, working with variables and data, and using functions, methods and events.

Next, you will learn intermediate JavaScript programming techniques that will build upon your knowledge and present solutions for more functional and exciting Web pages. These include using control structures for program flow, manipulating the JavaScript DOM, using language objects, creating expressions, and creating and using custom objects.

You will then apply JavaScript programming techniques to develop interactive forms, change HTML dynamically, create and use cookies, and explore security issues related to JavaScript. You will also learn about extensions to the JavaScript language, including JavaScript code libraries, Web APIs and advanced interactive Web applications with AJAX. Finally, you will learn throughout the course about tools and techniques for debugging and troubleshooting your JavaScript code.

By the end of this course, you will understand and use the most popular applications of JavaScript.
