Punch complexity in the face with RxJS

Modern front end programming is hard. Remember when all the data was loaded on the server and then rendered with one big bang? Now your page loads in data from 10 different API calls, that all come in at different times. Many of them depend on previous asynchronous calls, and then the users are always clicking on stuff! Trying to manage all of that can get complicated in a hurry. Well don't worry becuase RxJS is here to kick the feet out from under complexity, and replace your tangled rats nest of promises and callbacks with a few lines of elegant composition. Come learn about Observables from the ground up, and end by learning how to write RxJS like a pro.
