this.el = el;
this.load = load;
this.t = threshold;
this.el.addEventListener('scroll', () => {
const { scrollTop, scrollHeight, clientHeight } = this.el;
if (scrollHeight - scrollTop - clientHeight < this.t) this.load();
});
}
}
// Example placeholder (requires DOM scroll environment)
// new InfiniteScroll(container, () => console.log('load'));05
