# Feeling discouraged (chunky monkey assignment)

Hi all ,
I think I spend two days trying to figure this assignment out on my own.
It seems to work and correctly seperate the arr array into smaller arrays (when I add document.write statements ), but the code is not passing.

I can look at the hints or solutions , but that doesn’t really help me figure out why my code is wrong.
I hope someone is willing to take a look at it ,it’s a bit longer.

Thanks ``````function chunkArrayInGroups(arr, size) {
/*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.*/

let len = arr.length;
let numberOfArrs = len/size;
let zero =0;
let mainArrs = new Array();

chunkArrayInGroups.nextStep=0;
chunkArrayInGroups.newNextStep=0;

for(let i=zero;i<numberOfArrs;++i){

if(numberOfArrs === 2){

if(i === zero){
mainArrs.push([arr.slice(zero,size)]);
}else{
mainArrs.push([arr.slice(size,len)]);
}
} else {

if(i === zero){
mainArrs.push([arr.slice(zero,size)]);
} else if(i===1){

nextStep = size*2 ;
mainArrs.push([ arr.slice(size,nextStep)]);
} else {

newNextStep= nextStep+size;
mainArrs.push([arr.slice(nextStep,newNextStep)]);
nextStep=newNextStep;
}
}
}

return mainArrs;
}
``````
``````mainArrs.push([arr.slice(zero,size)]);
``````

You have several lines that look similar to the above line. You have wrapped `[` and `]` around the result of the slice method on arr. This has the effect of pushing a two-dimensional array into mainArrs instead of a one-dimensional array into mainArrs.

EDIT: I am not sure why you have written the following lines as you did.

``````chunkArrayInGroups.nextStep=0;
chunkArrayInGroups.newNextStep=0;
``````

Why not just declare two variables nextStep and newNextStep and assign 0 to both of them before the for loop?

Thank you , that solved it I was just confused about it needing to be an array of arrays.
And then I got lost in the details and thought the two variables needed to be static.
