Detect screen moving with JS after user has swiped it and ended the touch

const scrollElement = document.getElementById("scrollcontainer");
const scrollEndTime = 200 // time until callback fires when no scroll reaches

let scrollEndTimeout = null;

// Callback that fires when your scroll end has reached
function scrollEndCallback() {
    // Do whatever you want in here
    console.log("ScrollEnd")
}

scrollElement.addEventListener('scroll', () => {
    if (scrollEndTimeout !== null) {
        // clears the previous timeout that has been set in the scorll
        clearTimeout(scrollEndTimeout);
    }

    // in every scroll set a new timeout that gets cleared when the next scroll event appears or fires when no other reaches
    scrollEndTimeout = setTimeout(() => {
        scrollEndCallback();
    }, scrollEndTime);
});

<div id="scrollcontainer" style="height:120px;width:120px;border:1px solid #ccc;font:16px/26px Georgia, Garamond, Serif;overflow:auto;">
