How to return two 2d arrays from a function JavaScript Google script

Question

I have a function that produces two 2d arrays; how do I return both of them?

I can return two 1d arrays

function test() {
  do some stuff and get
  arr1 =["A',"B","C"]
  
  do some other stuff and get
  arr2 =["X","Y","Z"]


  return [arr1,arr2]
}

test[0]= arr1

test[1]=arr2

But if I have

function test() {
  do some stuff and get
  ary1 =[
         ["A',"B","C"],
         ["M',"N","O"]
        ] 
         

  do some other stuff and get
  ary2 =[
         ["X","Y","Z"],
         ["M',"N","O"]
        ] 
  return [ary1,ary2]
}

and I get

test[0] =["A',"B","C"]

test[1] =["X","Y","Z"]

Expected result:

test[0] =[
          ["A',"B","C"],
          ["M',"N","O"]
         ]

test[1] =[
          ["X","Y","Z"],
          ["M',"N","O"]
         ] 

how do I return ary1 and ary2?

I have to apologize for my poor English skill. Unfortunately, from your question, I cannot understand your expected values. So, when the values of ary1 and ary2 of your 2nd script are used, what are your expected values? — Tanaike

I think that in your script, test of test[0] and test[1] is the function. So, in this case, please modify test()[0] and test()[1].

function test() {
  ary1 = [["A", "B", "C"], ["M", "N", "O"]];
  ary2 = [["X", "Y", "Z"], ["M", "N", "O"]];
  return [ary1, ary2];
}

console.log(test()[0]);
console.log(test()[1]);

Note:

As additional information, in the case of test()[0] and test()[1], the script of test() is run 2 times. So, in this case, I thought that the following sample might be suitable.

function test() {
  ary1 = [["A", "B", "C"], ["M", "N", "O"]];
  ary2 = [["X", "Y", "Z"], ["M", "N", "O"]];
  return [ary1, ary2];
}

const values = test();
console.log(values[0]);
console.log(values[1]);

// or the following sample can be also used.
const [a, b] = test();
console.log(a);
console.log(b);
