Tell us what’s happening:
Your code so far
function chunkArrayInGroups(arr, size) {
var temp = [];
var result = [];
for (var a = 0; a < arr.length; a++) {
if (a % size !== size - 1)
temp.push(arr[a]);
else {
temp.push(arr[a]);
result.push(temp);
temp=[];
}
}
if (temp.length !== 0)
result.push(temp);
return result;
}

Could someone help explain what is happening in a few different parts of this code to me? I’m not able to understand it. I don’t know if my math or logic skills just suck.
Why do we need a temporary array and temporary result? Is the Temp to temporarily store parts of the sliced data from the array?
if (a % size !== size - 1) | I’m not understanding what this code means or what it does.
Why are we pushing the loop to temp only to set it back to empty after pushing it to result? What is the point?
temp.push(arr[a]);
result.push(temp);
temp=[];
Isn’t temp empty now? so what is it checking for in terms of the length?
if (temp.length !== 0)
Thank you
