// print the current page (the 1st page)
console.log(paginator.current());
// print the 10th page (`undefined` because it doesn't exists)
console.log(paginator.page(9));

// print the next page (the 2nd page)
console.log(paginator.next());
// print the previous page (the 1st page)
console.log(paginator.previous());

import { Paginator } from 'apaginator';
// create some fake data
const fakeData = Array.from(Array(14).keys());
