如何得到两个字符串数组的差异？

function getArrayDifference(arr1, arr2) {
  const set = new Set(arr1);
  const difference = [];

  for (let str of arr2) {
    if (set.has(str)) {
      set.delete(str);
    } else {
      difference.push(str);
    }
  }

  return {
    common: Array.from(set),
    difference: difference
  };
}

const array1 = ["apple", "banana", "orange"];
const array2 = ["banana", "grape", "kiwi"];

const result = getArrayDifference(array1, array2);
console.log("Common strings:", result.common);
console.log("Different strings:", result.difference);

Common strings: [ 'apple', 'orange' ]
Different strings: [ 'grape', 'kiwi' ]
