make it

var obj = {
    i: {
        want: {
            it: 'Oh I know you do...'
        }
    }
};
//var result = JSON.parse(JSON.stringify(obj)); //cloning the existing obj
var result = obj; //cloning the existing obj
var give = 'i.want.it';

//now split the give and iterate through keys
give.split(".").forEach(function(key){
  result = result[key];
});
console.log(result);
