Get total number of comps that are used in the opened project?

Question

Hi everyone!
Does anyone know how i can get the total number of comps in the project-panel or the total number of comps that are used in the opened project?
This is what i have so far, however it's not exactly what I am looking for:
for (var i = 1; i <= app.project.numItems; i++) {
    if (app.project.item(i) instanceof CompItem) {
        alert(i);

You can get the total number of comps with pretty much what you have
var numComps = 0;
for (var i = 1; i <= app.project.numItems; i++) {
    if (app.project.item(i) instanceof CompItem) {
        numComps++;
You could look at the usedIn attribute of each comp to see how many comps appear in other comps, but that won't identify your top-level comp. I'm not sure how you would do that unless you just bump the count by 1:
var numUsedComps = 0;
var numComps = 0;
for (var i = 1; i <= app.project.numItems; i++) {
    if (app.project.item(i) instanceof CompItem){
        numComps++;
        if (app.project.item(i).usedIn.length > 0) {
            numUsedComps++;
if (numComps > 0) numUsedComps++;
alert("number of comps = " + numComps + "\rnumber of used comps = " + numUsedComps);
