如何用函数中的数据填充数组？

function fillArrayWithData() {
  var data = [1, 2, 3, 4, 5];
  var array = [];

  for (var i = 0; i < data.length; i++) {
    array.push(data[i]);
  }

  return array;
}

def fill_array_with_data():
  data = [1, 2, 3, 4, 5]
  array = []

  array.extend(data)

  return array

def fill_array_with_data():
  data = [1, 2, 3, 4, 5]
  array = [x for x in data]

  return array
