Another aproach that you can utilize, is using .filter, look:

const paginate = function (array, index, size) {
        // transform values
        index = Math.abs(parseInt(index));
        index = index > 0 ? index - 1 : index;
        size = parseInt(size);
        size = size < 1 ? 1 : size;

        // filter
        return [...(array.filter((value, n) => {
            return (n >= (index * size)) && (n < ((index+1) * size))
        }))]
    }

var array = [
  {id: "1"}, {id: "2"}, {id: "3"}, {id: "4"}, {id: "5"}, {id: "6"}, {id: "7"}, {id: "8"}, {id: "9"}, {id: "10"}
 ]


var transform = paginate(array, 2, 5);

console.log(transform) // [{"id":"6"},{"id":"7"},{"id":"8"},{"id":"9"},{"id":"10"}]
