how to use object value as object name in javascript?

Question

how can i use the object value as object name

like this

$.each(columns, function(index, value) {
    var objectName = value.object; // need to pass this 
    to the next $.each
    //lets say i'm expecting objectName = x 
    $.each(values, function(i, v) {
        // console.log(v.x) ; // this works fine 
        console.log(v.objectName);
    });
});
