ES6中高效判断两数组元素是否完全一致（无视顺序）的方法

let identical = true;

const arr1 = [1, 2, 3];
const arr2 = [3, 2, 1];

if (arr1.length !== arr2.length) {
identical = false;
} else {
const sortedArr1 = arr1.sort();
const sortedArr2 = arr2.sort();
for (let i = 0; i if (sortedArr1[i] !== sortedArr2[i]) {
identical = false;
break;
}
}
}
