JavaScript -比较具有限制值/元素的两个数组

function compareArrays(array1, array2) {
  for (let i = 0; i < array1.length; i++) {
    if (array2.includes(array1[i])) {
      console.log(`数组1中的值 ${array1[i]} 存在于数组2中`);
    }
  }
}

const array1 = [1, 2, 3, 4, 5];
const array2 = [4, 5, 6, 7, 8];

compareArrays(array1, array2);

function compareArrays(array1, array2) {
  const commonValues = array1.filter(value => array2.includes(value));
  console.log(`两个数组中的相同值为： ${commonValues}`);
}

const array1 = [1, 2, 3, 4, 5];
const array2 = [4, 5, 6, 7, 8];

compareArrays(array1, array2);

function compareArrays(array1, array2) {
  const set1 = new Set(array1);
  const set2 = new Set(array2);

  const commonValues = new Set(
    [...set1].filter(value => set2.has(value))
  );

  console.log(`两个数组中的相同值为： ${[...commonValues]}`);
}

const array1 = [1, 2, 3, 4, 5];
const array2 = [4, 5, 6, 7, 8];

compareArrays(array1, array2);
