Chunky Monkey: Correct answer but incorrect format

Tell us what’s happening:

I can get the proper results as an array, but the formatting is incorrect and the answer is marked wrong. I had this happen in another array challenge too. If someone can point me as to what I’m messing up, it will probably fix both issues.

Thank you!

Your code so far
var all = [];
var stor = [];

function chunkArrayInGroups(arr, size) {

for (var i = 0; i < arr.length; i = i + size) {
stor = arr.slice(i,size + i);
all.push(stor);
stor = [];
}
return all;
}

//chunkArrayInGroups([“a”, “b”, “c”, “d”], 2);
//chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3);
//chunkArrayInGroups([0, 1, 2, 3, 4, 5], 2)
chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6, 7, 8], 2);

I’m not sure about the formatting, but I see this error: ReferenceError: all is not defined

I’m confused how it returns something then…

edit: when it copied over it excluded the first line

Awesome! Thank you very much!
