I have an array I would like to split in half. So I can position the first half on the right side and the second half on the left side.

I have used the splice function before:

var leftSide = arrayName.splice(0,2);

But not sure how to splice it in half no matter the size, because the array will change in size dynamically.

var half_length = Math.ceil(arrayName.length / 2);    



var leftSide = arrayName.slice(0,half_length);
