I have 2 javascript objects and I am trying to loop through one object and check whether the key exists in a second multidimensional object going one level deeper each time.

Here are the two objects

var check = {'scope':'instance', 'item':'body', 'property': 'background'}; 

var values = {'instance': {'body' : {'background': '000000'}}};


b.map(check, function(key){

     console.log(values[key]);
});

How am I able to check 1 level deeper in the values object each time? What I am trying to do is check the values object as follows:

• 1st values['instance']
• 2nd values['instance']['body']

• 3rd values['instance']['body']['background']

  Thanks
