Angular & IntersectionObserver API
The Intersection Observer API can be used to perform actions based on the visibility of an element within a viewport. This can be particularly useful for lazy-loading images, infinite scrolling, or react when an element comes into view.
Using vanilla JS:
let options = {
root: document.querySelector("#scrollArea"),
rootMargin: "0",
threshold: 1.0,
};
let observer = new IntersectionObserver(callback, options);
