This lesson introduces the concept of an Observable. We will see how similar it behaves to a function and what is the fundamental difference between them.
How do you pass a value into a new Observable using Create. I see a lot of examples of .onNext(42), but how would this value be passed in?
Wow. Thanks for making the comparison between functions and observables so easy to understand.
Was there supposed to be further explanation regarding using the call() method? There wasn't much more said about it in this video or in the rest of the course.
Hi Patrick. Towards the end of this video I pointed out a symmetry with functions and Observables, where .call and .subscribe are semantically equivalent. Both will invoke the lazy computation and produce value(s) that is(are) returned.
