Finding pathItems that have no fill and no stroke

Question

Hey Everyone,
So here's what I wrote to try and find and delete all pathItems within a document that lack a fill and lack a stroke.
var doc = app.activeDocument;
for (i=0; doc.pathItems.length>i;i++) {
    alert(doc.pathItems[i].name + " " + doc.pathItems[i].fillColor.name)
    alert(doc.pathItems[i].name + " "  + doc.pathItems[i].strokeColor.name)
        if (doc.pathItems[i].fillColor.name == 'undefined' && doc.pathItems[i].strokeColor.name == 'undefined') {
            alert("FOUND IT!")
            doc.pathItems[i].remove()
Then I tried this since it's typename is [GrayColor]
var doc = app.activeDocument;
for (i=0; doc.pathItems.length>i;i++) {
    alert(doc.pathItems[i].name + " " + doc.pathItems[i].fillColor.name)
    alert(doc.pathItems[i].name + " "  + doc.pathItems[i].strokeColor.name)
        if (doc.pathItems[i].fillColor.gray == 0 && doc.pathItems[i].strokeColor.gray == 0) {
            alert("FOUND IT!")
            doc.pathItems[i].remove()
But alas, neither seems to do the trick, the first one makes sense why it wouldnt work since it says that the color is "undefined" but it isnt a string called "undefined." So I'm not sure how to go about this at all now.
Any suggestions?

Also you're removing the items so it's better to go backwards:
for(var i=doc.pathItems.length-1; i>-1; i--){
