如何在js中比较两个数组并返回true

function compareArrays(arr1, arr2) {
  if (arr1.length !== arr2.length) {
    return false;
  }
  
  for (let i = 0; i < arr1.length; i++) {
    if (!arr2.includes(arr1[i])) {
      return false;
    }
  }
  
  return true;
}

const array1 = [1, 2, 3];
const array2 = [2, 1, 3];

console.log(compareArrays(array1, array2)); // Output: true

function compareArrays(arr1, arr2) {
  if (arr1.length !== arr2.length) {
    return false;
  }
  
  const set1 = new Set(arr1);
  const set2 = new Set(arr2);
  
  if (set1.size !== set2.size) {
    return false;
  }
  
  for (let item of set1) {
    if (!set2.has(item)) {
      return false;
    }
  }
  
  return true;
}

const array1 = [1, 2, 3];
const array2 = [2, 1, 3];

console.log(compareArrays(array1, array2)); // Output: true

function compareArrays(arr1, arr2) {
  return JSON.stringify(arr1) === JSON.stringify(arr2);
}

const array1 = [1, 2, 3];
const array2 = [2, 1, 3];

console.log(compareArrays(array1, array2)); // Output: true
