Example:

$(function(){
  $('#btn2').one('click', function(){
    var obj1 = 'A string', obj2 = {}, obj3 = new Object;
    $('#div2').append('Is obj1 plain JavaScript object? ' +  $.isPlainObject(obj1) + '<br />');
    $('#div2').append('Is obj2 plain JavaScript object? ' +  $.isPlainObject(obj2) + '<br />');
    $('#div2').append('Is obj3 plain JavaScript object? ' +  $.isPlainObject(obj3) + '<br />');
  });
});

Output:

Is obj2 plain JavaScript object? "true"
