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:
It looks like fromArray() has been deprecated.
Hi Steve, that is correct. The API fromArray() is not directly available, but one can still use from() which auto-detects what kind is the argument (array, Promise, etc) and under the hood may use fromArray or fromPromise, etc.
