使用JavaScript就地交织数组的值

function interleaveArrays(arr1, arr2) {
  const result = [];
  const maxLength = Math.max(arr1.length, arr2.length);

  for (let i = 0; i < maxLength; i++) {
    if (i < arr1.length) {
      result.push(arr1[i]);
    }
    if (i < arr2.length) {
      result.push(arr2[i]);
    }
  }

  return result;
}

const array1 = [1, 2, 3];
const array2 = ['a', 'b', 'c', 'd'];

const interleavedArray = interleaveArrays(array1, array2);
console.log(interleavedArray);
