尝试比较对象数组中的键

function haveSameKeys(arr1, arr2) {
  const keys1 = new Set(arr1.map(obj => Object.keys(obj).join(',')));
  const keys2 = new Set(arr2.map(obj => Object.keys(obj).join(',')));
  return keys1.size === keys2.size && [...keys1].every(key => keys2.has(key));
}

const array1 = [{a: 1, b: 2}, {a: 3, c: 4}];
const array2 = [{b: 5, a: 6}, {c: 7, a: 8}];

console.log(haveSameKeys(array1, array2)); // 输出：true

function compareValuesByKey(arr1, arr2, key) {
  return arr1.every((obj1, index) => obj1[key] === arr2[index][key]);
}

const array1 = [{a: 1}, {a: 2}];
const array2 = [{a: 1}, {a: 2}];

console.log(compareValuesByKey(array1, array2, 'a')); // 输出：true
