This is my own object traversal function and returning whether a object has a nested object or not (using recursion)

isNestedObjectMyVersion.js

function traverse (obj, callback) {  
  Object.keys(obj).forEach(function(value){
  	if (typeof obj[value] == 'object') {
    	traverse(obj[value],callback);
      callback(value,true);
    }
    else { 
    	callback(value,false) 
    }
 });
}

var myObj = {
  id: 1,
  name: 'joy',
  address : {
    street : 'abc',
    lane: {
      a : 1
    }
  }
};
traverse(myObj, function (value,status) {
  console.log(value+ " : " +status);
})

console.log(myObj);
