检查数组中的所有对象是否包含给定的键值(Javascript)

const objectsArray = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

const keyValueToCheck = { age: 30 };

function checkObjectsForKeyValue(array, keyValue) {
  return array.every(obj => 
    Object.keys(keyValue).every(key => obj.hasOwnProperty(key) && obj[key] === keyValue[key])
  );
}

const allObjectsHaveKeyValue = checkObjectsForKeyValue(objectsArray, keyValueToCheck);
console.log(allObjectsHaveKeyValue); // 输出: false，因为不是所有对象都有年龄为30

function checkObjectsForKey(array, key) {
  return array.every(obj => obj.hasOwnProperty(key));
}

const allObjectsHaveKey = checkObjectsForKey(objectsArray, 'age');
console.log(allObjectsHaveKey); // 输出: true，因为所有对象都有'age'键
