如何在不影响数组中其他值的情况下更新单个值？

function updateValueInArray(arr, targetIndex, newValue) {
  const newArr = [];
  for (let i = 0; i < arr.length; i++) {
    if (i === targetIndex) {
      newArr.push(newValue);
    } else {
      newArr.push(arr[i]);
    }
  }
  return newArr;
}

// 示例用法
const originalArray = [1, 2, 3, 4, 5];
const updatedArray = updateValueInArray(originalArray, 2, 10);
console.log(updatedArray);  // 输出：[1, 2, 10, 4, 5]
