Complex RxJS iterator - visible lines only

Question

We have more than 500 lines from the list for each request, sometimes it is 10, and sometimes huge.

I want to take this array and show only what is visible on the screen and hide everything else, but the user scrolls down, it displays other lines and hides the previous ones.

It's a little trickier, I watched the RxJS video, and Netflix was the same. I'm not sure which features to use for this effect.

Our code:

Observable.fromArray([0,1,2,.....500]).subscribe(row => show(row));
