Learn how to handle asynchronous work with ease! In this course, you'll use Native JavaScript Promises to write asynchronous code that is easy to read, easy to write and easy to debug.
Along the way, you'll be using Promises to make a webapp come to life!
We expect that students have built web apps in the past and they are familiar with the pitfalls of callback-heavy code. There is no HTML or CSS in this class.
JavaScript Skills Required:
.forEach
and .map
Other Requirements:
See the Technology Requirements for using Udacity.
Every web developer needs to be able to work with asynchronous code. Network requests, browser events, web workers and just about every else about the web happens asynchronously.
JavaScript developers normally rely on callbacks to execute async code, but Native JavaScript Promises offer a much easier solution. With Promises, error handling is streamlined and it becomes possible to flexibly chain lots of asynchronous work without creating a tangled mess of callbacks.
