https://egghead.io/courses/rxjs-beyond-the-basics-creating-observables-from-scratch RxJS Beyond the Basics: Creating Observables from scratch 38 minutes There are plenty of introductions to RxJS, but few resources that take you deep into the library, providing an accurate understand of what each piece performs.
In this course we will gain intermediate knowledge of RxJS, focusing on one aspect: how to create Observables. We will see how Observables compare to functions, how they compare to ES6 generators, what are the empty(), throw() and never() Observables, and other static factories that help in making Observable sequences.
Start following this course if you have a superficial understanding of RxJS, but want to gain confidence in using it.
If you're new to RxJS, we highly recommend this Async JS course from Jafar Husain to get a solid intro to the concepts. From there, you can watch this Introduction to Reactive Programming using RxJS, and you will be prepared for this course!
