Repeatedly generate different sets of quick replies from a products array

product-quickreplies.js

const productQuickreplies = (products, sliceSet, beginSlice, endSlice) => {
  
  // slice the elements of the array to the desired set size
  let slicedProducts = products.slice(beginSlice, endSlice);
  
  // form an array of quick replies with title and payload
  let quickReplies = slicedProducts.map(product => {
    return {
      "content_type": "text",
      "title": product.title,
      "payload": product.title
    };
  });
  
  // Check if the current set is not the last one
  if (endSlice < products.length) {
    // add an extra quick reply that will display the next set
    quickReplies.push({
      "content_type": "text",
      "title": "Next",
      "payload": `next_${beginSlice + sliceSet}_${endSlice + sliceSet}`
    });
  }
  return quickReplies;
