VUE 深度比较对象是否完全相等

function deepEqual(obj1, obj2) {
  if (obj1 === obj2) return true;
  if (typeof obj1 !== "object" || typeof obj2 !== "object") return false;
  const keys1 = Object.keys(obj1);
  const keys2 = Object.keys(obj2);
  if (keys1.length !== keys2.length) return false;
  for (let key of keys1) {
    if (!this.deepEqual(obj1[key], obj2[key])) return false;
  }
  return true;
};
