intersectionobserver isintersecting

// =========== Intersection Observer isIntersecting =====================

// This means, when the Observer intersects with the Element 
// It returns TRUE or FALSE
// Here is a small example:

const box = document.querySelector(".box");
const callbackFunction = function(entries){
  	if(entries[0].isIntersecting) { 
    	entries[0].target.children[0].classList.add("appear");
      	// Stop observating because we made the Element appear
    	observer.unobserve(fadeElement);
  	}
};

const observer = new IntersectionObserver(callbackFunction, {
	// Here you can add some Options you can find on the documentation
});
observer.observe(box)

Intersectionobserver

/* 
The Intersection Observers lets you know whenever an Element becomes Visible to the end User. 
(This means when you scroll down on a page, the Intersection Observer sees what you see)
*/
const box = document.querySelector(".box");
const callbackFunction = function(entries){
  	// Use Console logs, try thinking yourself what this all could be
	console.log(entries);
  	console.log(entries[0]);
};

// The Function runs(gets triggered) whenever the box comes into view and also when it goes out of view
const observer = new IntersectionObserver(callbackFunction, {
	// Here you can add some Options you can find on the documentation
});

// To make this work we need the observe() method and pass our target element.
observer.observe(box)
