Along the way, you'll be using Promises to make a webapp come to life!
Why Take This Course? 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.
### Lesson 2 - Chaining Promises
* Creating sequences of async work manually
* Advanced error handling
* Techniques for generating sequences of async work with array methods
Throughout the course (mostly in the second lesson), you'll be using Promises to load data into the Exoplanet Explorer app, which was designed to help people learn a little bit about planets around other stars.
