const obj1 = { a: 1, b: 2, c: { d: 3 } };
const obj2 = { a: 1, b: 3, c: { d: 4 } };
compareObjects(obj1, obj2);
// { b: 3, c: { d: 4 } }
const obj1 = { a: 1, b: 2, c: { d: 3 } };
const obj2 = { a: 1, b: 3, c: { d: 3 } };
compareObjects(obj1, obj2, 'common');
// { a: 1, c: { d: 3 } }
const obj1 = { a: 1, b: 2 };
const obj2 = { a: 1 };
compareObjects(obj1, obj2);
