How to change target track if overlap exists

Hi there,

I'm working on a script that learns the location, start, end, duration and name of a number of clips on a timeline. I'm wanting to paste those clips to a new track(s) whilst catching overlaps. I have the code to calculate if an overlap exists but i'm stuck at how to implement updating the paste track on each clip and subsequent clip that is affected.

function checkForOverlaps() {
    //sort sceneClips into ascending order based on targetTrack
    sceneClips.sort((a, b) => a.targetTrack - b.targetTrack);
    //calculate if overlap exists
    function doesOverlapExist(a, b) {
        return (a.start < b.end && b.start < a.end);
    }

sceneClips is my list of clips that the script has learned.

How do I run the function doesOverlapExist on each object in the array? This is the closest i've got.

    sceneClips.forEach(function (element) {
        element.overlap = doesOverlapExist();
    });

Once the sceneClips list has been updated with any overlaps, how do I then add 1 (+1) to paste track for clips that have overlaps and all subsequent clips?

function updatePasteTrack() {
    sceneClips.forEach(function (element) {
        if (sceneClips.overlap == True) {
            element.targetTrack = element.targetTrack + 1;
        } else {
            element.targetTrack = element.targetTrack
        }
    });
    return sceneClips;
}

This is where i've got so far.

Any help greatly appreciated.

Many thanks,

Iain
