Learn to work with Asynchronous JavaScript and XML (AJAX) when developing advanced web applications in this course. AJAX enables you to create a whole new level of user interaction and responsiveness when building your next-generation web applications. You will cover a number of intermediate and advanced tools and techniques using object-oriented JavaScript, XML, CSS, XSLT, and various server-side technologies. You will learn the top new privacy rules and regulations that impact your clients, and you will learn to use additional tools and techniques, including Document Object Model (DOM) Inspector, Firebug, and JavaScript Object Notation (JSON).
