检查对象数组是否具有以下属性

function hasProperties(arr, properties) {
  return arr.every(obj => properties.every(prop => obj.hasOwnProperty(prop)));
}

// 示例
const objects = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 }
];

const propertiesToCheck = ['name', 'age'];
console.log(hasProperties(objects, propertiesToCheck)); // 输出: true

function hasAnyProperties(arr, properties) {
  return arr.some(obj => properties.every(prop => obj.hasOwnProperty(prop)));
}

// 示例
const objects = [
  { name: 'Alice', age: 25 },
  { name: 'Bob' }
];

const propertiesToCheck = ['name', 'age'];
console.log(hasAnyProperties(objects, propertiesToCheck)); // 输出: true

function hasProperties(arr, properties) {
  for (let i = 0; i < arr.length; i++) {
    const obj = arr[i];
    let allPropsExist = true;
    for (let j = 0; j < properties.length; j++) {
      if (!obj.hasOwnProperty(properties[j])) {
        allPropsExist = false;
        break;
      }
    }
    if (allPropsExist) {
      return true;
    }
  }
  return false;
}

// 示例
const objects = [
  { name: 'Alice', age: 25 },
  { name: 'Bob' }
];

const propertiesToCheck = ['name', 'age'];
console.log(hasProperties(objects, propertiesToCheck)); // 输出: true
