[removed] How to detect if browser window is scrolled to bottom?

Question

I need to detect if a user is scrolled to the bottom of a page. If they are at the bottom of the page, when I add new content to the bottom, I will automatically scroll them

The accepted answer did not work for me. This did:

const element = document.createElement('div');
document.body.appendChild(element);
document.addEventListener('scroll', () => {
    const viewportHeight = window.innerHeight;
    const distance = element.getBoundingClientRect().top;
    if (Math.floor(distance) <= viewportHeight) {
        console.log('yep')
    } else {
        console.log('nope')
    }
})
