Splitting an array into more than one array

Question

I have a dynamic created array:

var myArray = ['content_1','content_2','content_3','content_4'];

Other times my array could have more items in as such:

var myArray = ['content_4','content_4','content_new','content_new','content_new','content_new','content_new'];

My if statement looks like:

if (myArray.length > 8) { //then do something }

If myArray has more then 8 items in the array, create a new one, each array can only hold 8 items though. So my first array could have 40 items in, 20 items in, or more... I never know, how could I split these into dynamic arrays, is there a way I can do this?

After the 8th item in myArray push those 8 into a new array, then the next 8 (if applicable) and so forth

You could have a look at the source code of Lodash's `_.chunk` method. https://lodash.com/docs#chunk — bendulum, Jan 14 '16 at 15:13
thanks dude! @bendulum been banging my head with this for awhile. I'll definitely check the link out — pourmesomecode, Jan 14 '16 at 15:15
a quick note, your if statement should say `if(myArray.length > 8){/* Do Something */ }` — AGE, Jan 14 '16 at 15:15
@bendulum just wanted to jump on and thank you again! That `_.chunk` method worked brilliant! Thanks a lot! — pourmesomecode, Jan 15 '16 at 09:52

You'd either have to store your arrays in another array or create a new variable for each array. Personally I'd use an array to store all the arrays so you can still look through all of them when you need to.

var arrays = [['item', 'item'], ['item','item']];

if(arrays[arrays.length].length === 8) {
    arrays.push(['new array']);
}

Obviously this won't work for every scenario but it would have to be something similar.
