LazyForEach Usage
LazyForEach iterates over provided data sources and creates corresponding components during each iteration. When LazyForEach is used in a scrolling container, the framework creates components as required within the visible area of the scrolling container. When a component is out of the visible area, the framework destroys and reclaims the component to reduce memory usage. Proper use of LazyForEach can effectively improve page load speeds, by shortening the length of data loaded at once and minimizing resource usage.
