尝试打印或回显数组中的数组

function printNestedArray(arr) {
  for (let i = 0; i < arr.length; i++) {
    if (Array.isArray(arr[i])) {
      printNestedArray(arr[i]);
    } else {
      console.log(arr[i]);
    }
  }
}

const nestedArray = [1, [2, 3], [4, [5, 6]]];
printNestedArray(nestedArray);

def print_nested_array(arr):
  for item in arr:
    if isinstance(item, list):
      print_nested_array(item)
    else:
      print(item)

nested_array = [1, [2, 3], [4, [5, 6]]]
print_nested_array(nested_array)

import java.util.Arrays;
