re: How to fade in content as it scrolls into view VIEW POST

Great example, especially since the so-called "simple example" on MDN is actually really complicated!

I'm still wondering why you are creating a new IntersectionObserver() for each component? In most online examples the observable elements are added to one single IntersectionObserver:

let observer = new IntersectionObserver(...)
let mythings = document.querySelectorAll('thing')
mythings.forEach(thing => {
    observer.observe(thing)
})
 

Hi!

I could've created a single intersection observer too, but to be honest it doesn't matter too much. If you have hundreds of things you want to fade in - sure, optimize it. I think the way I wrote it is a bit easier to understand from a beginner's point of view.
