JavaScript array slice example

In the example, we create two slices.
const nums = [2, -3, 4, 6, -1, 9, -7];

const res = nums.slice(3);
console.log(res);

const res2 = nums.slice(2, 4);
console.log(res2);
We create a slice from index 3 until the end of the array:
const res = nums.slice(3);
We create a slice from index 2, to index 4; the ending index is non-inclusive:
const res2 = nums.slice(2, 4);
This is the output:
[ 6, -1, 9, -7 ]
[ 4, 6 ]
