# mergeSort

Core/mergeSort.js 55
A stable merge sort.

##### Example:

    // Assume array contains BoundingSpheres in world coordinates.
    // Sort them in ascending order of distance from the camera.
    var position = camera.positionWC;
    Cesium.mergeSort(array, function(a, b, position) {
        return Cesium.BoundingSphere.distanceSquaredTo(b, position) - Cesium.BoundingSphere.distanceSquaredTo(a, position);
    }, position);
