How to divide an array in half in JavaScript
How can you divide an array in 2 parts, divided exactly in the middle?
Use the Array instance slice() method:
const list = [1, 2, 3, 4, 5, 6]
const half = Math.ceil(list.length / 2);
const firstHalf = list.slice(0, half)
const secondHalf = list.slice(half)
If the list contains an even number of items, the result is split with exactly half the items.
If the number is odd, for example
[1, 2, 3, 4, 5]
The result will be
[ 1, 2, 3 ]
[ 4, 5 ]
