Javascript array, for every increment create a nested array

Question

I have an array which always has a length of 50, which looks like so:

var array = [
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 'item',
 ...
];

What I need to do is loop through that array and create a nested array every 5 items, so the end result will be array containing 10 nested arrays which contain 5 items each, looking something like:

var array = [
 [
 'item',
 'item',
 'item',
 'item',
 'item'
 ],
 [
 'item',
 'item',
 'item',
 'item',
 'item'
 ],
 [
 'item',
 'item',
 'item',
 'item',
 'item'
 ],
 [
 'item',
 'item',
 'item',
 'item',
 'item'
 ],
 ...
];

I've tried quite a few things which always ends up in a complete mess of spaghetti loops, any help would be greatly appreciated. I'm even open to using jQuery if needs be.

• technophobia: Post your spaghetti, we're quite the supportive group here.
• b_dubb: Your comment reads like you only want every fifth element in the first array to have a nested array. Is that right?
• Namit Singal: just splice the array. :)

Answer 1

var array = ['item','item','item','item','item','item','item','item','item','item','item','item','item'];
var new_arr = [];
while(array.length) new_arr.push(array.splice(0,5));
console.log(new_arr);

• Tom: Ended up going with this, worked a treat, thanks a bunch!

Answer 2

Just have one for loop.

var temp=[], newArray=[];
for(i=0;i<array.length;i++){
 temp.push(array[i]);
 if(temp.length==size){//size in your case = 5
 newArray.push(temp);
 temp=[];
 }
}
