如何将具有重复键的对象序列合并为一个？

function mergeObjects(objects) {
  const merged = {};

  objects.forEach(obj => {
    for (const key in obj) {
      if (obj.hasOwnProperty(key)) {
        if (merged.hasOwnProperty(key)) {
          // 根据需求选择合并策略，这里使用替换
          merged[key] = obj[key];
        } else {
          merged[key] = obj[key];
        }
      }
    }
  });

  return merged;
}

// 示例用法
const objects = [
  { id: 1, name: 'John' },
  { id: 2, age: 25 },
  { id: 1, email: 'john@example.com' }
];

const mergedObject = mergeObjects(objects);
console.log(mergedObject);
