Advanced Asynchronous JavaScript

Learn how to build and manage asynchronous programs to become an effective JavaScript programmer. Join Jafar Husain - the Cross-Team Technical Lead for the Netflix UI and architect of its UI data platform as he takes you beyond the fundamentals of asynchronous JavaScript to introduce you to new features and techniques that will help you reduce code and create smarter applications. This class is for developers with an intermediate knowledge of JavaScript. At a minimum you must understand how to create functions, use loops, create JS Objects, and how function scope works. You should also have taken Jafar's Asynchronous JavaScript course.
