Convert JavaScript Values to RxJS Observables

The of() operator essentially converted a list of arguments to an Observable. Since arrays are often how we structure list of things in JavaScript, we should have a way of transforming arrays into Observables.

This lesson teaches how you can convert from Arrays to Observables, from Promises to Observables, and from Iterators to Observables. We will look at the API RxJS has for doing that: from, fromPromise, and fromArray.
