scrollTo speed/duration setting

Question

Is there a way to speed up the behavior speed of scrollTo?

I had a stab in the dark at speed and duration but don\'t work!

Answer 1

Working solution using Promise:

function scrollDelay(ms) {
    return new Promise(res => setTimeout(res, ms));
}

document.getElementById("slow-scroll-demo-button").onclick = async function() {
    for (var y = 0; y <= 4200; y += 100) {
        window.scrollTo({top: y, behavior: 'smooth'})
        await scrollDelay(100)
    }
}

Trick to introduce delay in scrolling:

1. Create an async function called scrollDelay() that spends time by calling a promise

2. Call the scrollDelay along with scrollTo in a for loop
