Learning how to build and manage asynchronous programs is perhaps the most important part of becoming an effective JavaScript programmer. Unlike most programming languages, JavaScript is single-threaded. As a result, JavaScript programs must use async APIs to stay responsive to user input while performing long-running tasks like server requests and animations. You can't get very far in a JavaScript program without running across an asynchronous API. It is possible to build most asynchronous programs using a handful of simple functions. We will learn why most JavaScript developers approach asynchronous programming the wrong way, and how to avoid these common mistakes. By the end of these lessons you will know the tools, concepts, and libraries required to be an asynchronous programming ninja!
