For this you need what's called a recursive function. The function keeps calling itself, working all the way down the chain of folders until it gets to the last subfolder with no contents and removes it. Then as you fall back through each recursion, any folders that now contain no items (because the subfolders have just been removed) will also be deleted.

function removeFolders(theFolder) {

// loop from last to first item so removing a folder won't affect the index

for (var i = theFolder.numItems; i > 0; i--) {

if (theFolder.item(i) instanceof FolderItem) {

// if subfolder contains items, enter recursive function again using the subfolder

if (theFolder.item(i).numItems > 0) removeFolders(theFolder.item(i));

// if either it never contained any items, or the contents has now been removed after leaving the later recursions, delete the folder

if (theFolder.item(i).numItems == 0) theFolder.item(i).remove();

}

// enter function for the first time using the root folder

removeFolders(app.project);
