In this lesson we will learn about potential problems that may arise when using Observable.create, a low-level function for creating Observables. In its place, we will use easier helper functions that create Observables in a safe manner.

How can listen to different events? For example, I have function with a callback and when the callback is called I want the Observale listen for that call. At this point fromEvent just lister for click, windowresize, etc.
