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.

3

What do you mean by “make a decision”? It should return a value and the value will be an array. Your function is not returning anything at the moment. You are using console.log to display something to the console, but that is not the same as returning a value.

4

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

5

return is not a function. It is a key word in JavaScript. I suggest you review the Basic JavaScript section where the return statement is first introduced.

6 
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

That is because you are returning:

[ [ [ 0, 1, 2 ] ], [ [ 3, 4, 5 ] ] ]

instead of:

[ [ 0, 1, 2 ] , [ 3, 4, 5 ] ]

However, what if size were 2 in instead of 3? You are attempting to hard code temp, when instead you should be “building” it from an empty array [ ].

8

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?

You should have already learned about the slice method which allows you to return “part” of an existing array. If you could take the “parts” of a a certain size and “push” them into a new array, that is an approach you could take. If you do not remember the slice method, see below for the challenge where it was introduced.

Thank you.

I did not understand the condition correctly.
I am Russian, I decide with a translator)))

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