Support for vanilla javascript

[tusharnaresh]

I was trying to use virtual in core js project but i am unable to make it work. Even after providing a valid scrollable element in getScrollElement function, the scrollToFn function never triggers and scrollElement inside VIrtualizer instance is null.
Here is the link to my implementation

Any help would be much appreciated.

Hi, you also need to provide observeElementRect, observeElementOffset, then after instance is created call instance._willUpdate() it will call provided options and setup the virtualizer. Something like https://stackblitz.com/edit/js-yc7vby?file=index.js,style.css,index.html

There seems to be one issue in the above implementation, I observed that in this case the number of elements in scroll container do not get limited. Even though I am viewing 5 elements on the container at a time i can see thousands of elements in my html elements.
Here is the link for the implementation:

It's because you don't remove items that are no longer visible.
