[JAVA] Convert a multidimensional list (array) to one dimension

Create a new empty list (array) and copy the original elements one by one.

For python

test.py



# coding: utf-8

animal_list = ["Dog", ["Persia", "Munchkin", "Scottish fold"], "Human", ["hamster,Capybara"]];
new_list = []

for animal in animal_list:
    if type(animal) == list:
        new_list.extend(animal)
    else:
        new_list.append(animal)
        
print(new_list)

For js (gas)

test.gs


function make_array() {
 
  var array = ["Dog", ["Persia", "Munchkin", "Scottish fold"], "Human", ["hamster,Capybara"]];
  var new_array = [];
  
  for (var i = 0; i <= array.length - 1; i++) {
    if (typeof(array[i]) == "object") {
      array[i].map(function(text) { new_array.push(text) });
    } else {
      new_array.push(array[i]);
    }
  }
  
  Logger.log(new_array);

}

-The list is variable (there is no need to determine the size), but the array is invariant. (It is necessary to decide the size at the time of declaration) ・ Is it necessary to determine the size of the array in js?
