Discussion on: Deeply Compare 2 Objects with Recursive Function in JavaScript

[zlm11]

Good article,however there is one problem, as Object.keys not include unenumerable properties, so if one obj has unenumerable property but the other not, the result expected false but true.

let obj3 = {
  name: "Rahim",
  additionalData: {
    instructor: true,
    favoriteHobbies: ["Playing Cricket", "Tennis", "Coding"],
    citiesLivedIn: ["Rajshahi", "Rangpur", "Joypurhat"]
  }
};
Object.defineProperty(obj3, 'noneEnumble', {
  value: 123,
  enumerable: false
});

let obj4 = {
  name: "Rahim",
  additionalData: {
    instructor: true,
    favoriteHobbies: ["Playing Cricket", "Tennis", "Coding"],
    citiesLivedIn: ["Rajshahi", "Rangpur", "Joypurhat"]
  }
};
console.log(deepComparison(obj3, obj4));
console.log(obj3.noneEnumble);

Thank you. Now, I am using Object.getOwnPropertyNames() instead of Object.keys() to solve the problem.
