// Write a function called validateKeys. This function takes two arguments, 'object' and 'expectedKeys'. 
// 'object' is an object that we want to valdiate keys for. 'expectedKeys' is an array of keys that we EXPECT TO FIND 
// on the object.

// validateKeys should return false if 'object' contains extra keys not in 'expectedKeys' or missing keys
// validateKeys should return false if 'object' contains different keys than in 'expectedKeys'
// ...therefore,
// validateKeys should return true if object has all of the keys from expectedKeys and no additional keys



// running the function with `objectA` and `expectedKeys`
// should return `true`
var objectA = {
  id: 2,
  name: 'Jane Doe',
  age: 34,
  city: 'Chicago'
}

// running the function with `objectA` and `expectedKeys`
// should return `false`
var objectB = {
  id: 3,
  age: 33,
  city: 'Peoria'
}

// ********** MY SOLUTION HERE *****************

// object = argument thats an object
// expectedKeys = argument thats an array of keys

var expectedKeys = [
  'id', 'name', 'age', 'city'
];

function validateKeys(object, expectedKeys) {  
    if (Object.keys(object).length !== expectedKeys.length) {
    return false;
  }
    for (var i=0; i<expectedKeys; i++) {
      if (Object.keys(object) !== expectedKeys[i]);     
      return false;
    }
  return true;
}

// For some reason I got it to work with 2nd argument in loop logic ' i<expectedKeys ' and doesn't
// work with ' i<expectedKeys.length ' so now Im more confused


// Remember to use logic operators: ! , !== , ===


// 1. First return the 'false' statements by disqualifying
//    if arg1.length !== arg2.length return false
//
// 2. Validate if keys in arg1 (the object) match keys (or items in array) in arg2 
//    keys in arg1 !== items in arg2 - return false
//   
//    a. for..in loop iterating expectedKeys
//    b. if arg1 content doesn't match arg2 content        
//
// 3. If non of the above then its true
//     return true;

// Curriculum Solution uses the .find() method

function validateKeys(object, expectedKeys) {
  if (Object.keys(object).length !== expectedKeys.length) {
    return false;
  }
  
  for (var i; i<expectedKeys.length; i++) {
    if (!Object.keys(object).find(function(key) {
      return key === expectedKeys[i];
      })) {
      return false;
    }
