how to space out key-frames evenly?

Hi there, Use this Script.

function adjustKeyframeSpace() {
    var selectedLayers = app.project.activeItem.selectedLayers;
    if (selectedLayers.length == 0) {
        alert("Please select a layer with keyframes to run this script");
        return;
    }
    var selectedProperties = selectedLayers[0].selectedProperties;
    if (selectedProperties.length == 0) {
        alert("Please select a property with keyframes to run this script");
        return;
    }
    var selectedKeyframes = selectedProperties[0].selectedKeys;
    if (selectedKeyframes.length == 0) {
        alert("Please select some keyframes to run this script");
        return;
    }

    var keyframeDuration = selectedProperties[0].keyTime(selectedKeyframes[selectedKeyframes.length - 1]) - selectedProperties[0].keyTime(selectedKeyframes[0]);
    var keyframeInterval = keyframeDuration / (selectedKeyframes.length - 1);

    for (var i = 0; i < selectedKeyframes.length; i++) {
        var newKeyframeTime = selectedProperties[0].keyTime(selectedKeyframes[0]) + (keyframeInterval * i);
        var easeIn = selectedProperties[0].keyInTemporalEase(selectedKeyframes[i])[0];
        var easeOut = selectedProperties[0].keyOutTemporalEase(selectedKeyframes[i])[0];
        var value = selectedProperties[0].valueAtTime(selectedProperties[0].keyTime(selectedKeyframes[i]), true);
        selectedProperties[0].removeKey(selectedKeyframes[i]);
        selectedProperties[0].setValueAtTime(newKeyframeTime,value);
        selectedProperties[0].setTemporalEaseAtKey(1, [easeIn], [easeOut]);
    }
}
adjustKeyframeSpace();
