Nice information, but moving mouse around quickly. it distracts and disturb the user to understand the concept, when some useful info is trying to say.

You don't need a library to adaptively render lists. You can just make it yourself.

[@josephmathew333]

how

[@AshtonMotana]

​@@josephmathew333 My file is only 16kb and has plenty of comments so could be smaller, doesn't take a lot of code. is reusable and also auto fetches data for any list component. create a scroll tracker function, with onScroll, that calls an external function, from that external function use a while loop with the run condition of "start" === "start", that runs at 100 millisecond intervals. This will be an infinite loop but won't freeze the browser. with the while loop constantly running you'll need to use the DOM to read and update data for the loop to know the start and end range of the data array slicer. Pass react setState... into the while loop function so the logic in your while loop can update the state data for the array slicer that resides in the rendering component. You'll need to have a top and bottom element that does not scroll with the list as you'll need to track the bottom and top of the list relative to those fixed elements and have the logic for scroll up and down, If bottom or top of list is x amount of pixels from the top or bottom of the viewport, then increment value for start and end range of the array slicer. That's the very basic. Generally, think of how you'd track motion, and distance. Object distance is relative to a fixed object position. If/when you create an array within the wile loop that determines if you're scrolling up or down or not scrolling at all, you can write an if condition that will then stop the loop from running, until you scroll again.

Don't reinvent the wheel for no reason

[@AshtonMotana]

@sayochikun3288 I had plenty of good reason and it works very well.
