JavaScript -返回两个对象之间的差异？

function getObjectDifference(obj1, obj2) {
  let differences = {};

  function compareObjects(objA, objB, path = '') {
    for (let key in objA) {
      let newPath = path ? `${path}.${key}` : key;
      if (objB.hasOwnProperty(key)) {
        if (typeof objA[key] !== typeof objB[key]) {
          differences[newPath] = { obj1: objA[key], obj2: objB[key] };
        } else if (typeof objA[key] === 'object' && objA[key] !== null && objB[key] !== null) {
          compareObjects(objA[key], objB[key], newPath);
        } else if (objA[key] !== objB[key]) {
          differences[newPath] = { obj1: objA[key], obj2: objB[key] };
        }
      } else {
        differences[newPath] = { obj1: objA[key], obj2: undefined };
      }
    }

    for (let key in objB) {
      let newPath = path ? `${path}.${key}` : key;
      if (!objA.hasOwnProperty(key)) {
        differences[newPath] = { obj1: undefined, obj2: objB[key] };
      }
    }
  }

  compareObjects(obj1, obj2);
  return differences;
}

// 示例使用
const obj1 = { a: 1, b: { c: 3, d: 4 }, e: 5 };
const obj2 = { a: 1, b: { c: 3, d: 5 }, f: 6 };

console.log(getObjectDifference(obj1, obj2));
