Basic Algorithm Scripting: Chunky Monkey HELP

JavaScript
1 
function chunkArrayInGroups(arr, size) {
var arr1=arr.slice(0,size);
var arr2=arr.slice(size,);
     var temp = [[], []];
      temp[0].push(arr1);
      temp[1].push(arr2);

console.log(temp);
}
chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3);

Tell me why the program does not make such a decision.

Write a function that splits an array (first argument) into groups the length of size (second argument) and returns them as a two-dimensional array.

with return() the same does not pass the test. I found the problem, but I don’t understand why this happens.

function chunkArrayInGroups(arr, size) {
var arr1=arr.slice(0,size);
var arr2=arr.slice(size,);
     var temp = [[], []];
      temp[0].push(arr1);
      temp[1].push(arr2);

return temp;
}
chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3);

but even so does not work

and there is an option how to make my code work? Without changing the meaning. I can not find on the Internet. How to add two arrays into one, but so that they are two?

Thank you.

I did not understand the condition correctly.

With splice () it turned out, but only for a special case.
