Using string from variable as property name for JSON in Javascript?

Question

So I\'m grabbing a JSON via AJAX, but need to re-configure it. Part of that means using a string contained in a variable as the property name of a nested object.

But

Use the [] syntax to resolve a variable as a property name. This might require an intermediary {}:

$.get('folder_get.php', function(data){
    var theList = $.parseJSON(data);
    $.each(theList, function(parentFolder, files) {
        var fileList = [];
        $.each(files, function(url, name) {
            thisGuy.push({fileURL: url, fileName: name});
        });

        // Make an object    
        var tmpObj = {};
        // And give it a property with the current value of parentFolder
        tmpObj[parentFolder] = fileList;
        // Then push it onto the array
        pvm.exerciseList.push(tmpObj);
    });
});
