Notes
When using this component in real projects, it is important to set itemKey and loadCount properly for optimal performance and accurate data updates.
itemKeyis the unique identifier for each list item. During data updates, the component will locate and update the corresponding item based onitemKey, ensuring correct data mapping and rendering.loadCountdetermines the number of items loaded per batch. The default value is1, but it is recommended to set it to the maximum number of items that can fit in the visible area. This improves performance by reducing unnecessary rendering calculations, instead of loading only1item at a time and repeatedly checking whether the visible area is filled.
