Compounding existing paths into compoundpathitems with javascript

Question

Im not very familiar with Scripting for Illustrator, so please forgive me if Im overlooking something obvious, but I cant seem to find an easy way to compound existing pathItems into a compoundPathItem; do I have to collect the pathPoint-properties of the existing path and create a new path within a new compound path?
Any help appreciated.

I had a hard time figuring this one out too, but stumbled upon the solution. This snippet of code loops through all of the layers of the file, creates a new compound path in each layer, loops through all of the paths in the layer (ignoring the new compound path) and moves them to the compound path. You have to reset the counter as the number of items in the layer changes each time you move an item to the compound path.
var NumberOfLayers = thisFile.layers.length;
for(i = 0; i < NumberOfLayers; i ++) {
  var newCompPath = thisFile.layers[i].compoundPathItems.add();
  newCompPath.name = "MyCompPath";
  var NumberOfItemsInLayer = thisFile.layers[i].pageItems.length;
  for(j=0;j<NumberOfItemsInLayer;j++)  {
    var SelItems = thisFile.layers[i].pageItems[j];
    if (SelItems.name != "MyCompPath")   {
      SelItems.moveToBeginning(newCompPath);
      var NumberOfItemsInLayer = thisFile.layers[i].pageItems.length;
      j = 0
