如何从父数组创建新数组？

function createNewArray(parentArray) {
  var newArray = [];
  for (var i = 0; i < parentArray.length; i++) {
    newArray.push(parentArray[i]);
  }
  return newArray;
}

def create_new_array(parent_array):
  new_array = parent_array[:]
  return new_array

import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
    int[] parentArray = {1, 2, 3, 4, 5};
    int[] newArray = Arrays.copyOf(parentArray, parentArray.length);
    System.out.println(Arrays.toString(newArray));
  }
}
