What you can see from the preceding timeline of keyUps is that it is a continuous stream of data where the keyUp event can happen at any time; after all, the user decides when to press those keys. Remember the Observable code we wrote, containing the setTimeout? That code was able to tell a concept Observer that every time 2 seconds passed, another value should be emitted. What's the difference between that code and our keyUps? Nothing. Well, we know how often a timer interval is triggered, and with keyUps, we don't really know because it is not in our hands. But that is really the only difference, which means keyUps can be thought of as an Observable as well:

let key = document.getElementId('.search');

/*

we assume there exist a button in the DOM like this

<input class="search" placeholder="searchfor"></input>

*/
