A way of creating a frontend pagination

pagination.js

// here is an array of 120 items
const items = Array.from({length: 120}, (_, index) => index);
console.log("items ->", items);

function createPagination(items, itemsPerPage) {
  const numberOfPages = Math.ceil(items.length / itemsPerPage);

  return Array.from({length: numberOfPages}, (_, index) => {
    const startIndex = index * itemsPerPage;
    return items.slice(startIndex, startIndex + itemsPerPage);
  });
}

// the outcome is an array of arrays, that is what we wanted for a frontend pagination
const paginatedItems = createPagination(items, 14);
console.log("paginatedItems ->", paginatedItems);
