I'm going to add filter which would be sorting shop products by the price. I didn't know how exactly I should do that so I found the code but something is wrong cos it doesn't work property. products are not set from lowest to highest:

First is my index.js which shows all my products and objects

module.exports = ({ products }) => {
    const renderedProducts = products
    .map(product => {
      return `
<div data-price="" class="image shopProduct ${product.category.join(' ')} ${product.fabric.join(' ')} ${product.bulb}" >  
        <img class="" src="data:image/png;base64, ${product.image}"/>
        <h3 class="subtitle">${product.title} <br>${product.model}</h3>
        <h5 >${product.price.toFixed(2)} zł</h5>
        <form action="/cart/products" method="POST">
          <input hidden value="${product.id}" name="productId" />
          <button class="button has-icon is-inverted">Dodaj do
          <i class="fa fa-shopping-cart"></i></button>
        </form>
        </div>
</div>
 <select class="sorting">
  <option value="Sort">Sortuj</option>
  <option value="SortA">Nazwa A-Z</option>
  <option value="Sort">Nazwa Z-A</option>
  <option value="high">Cena rosnąco</option>
  <option value="low">Cena malejąco</option>
</select>
//This is my javascript code 
<script>
let field = document.querySelector('.images');
let div = Array.from(field.children)
let select = document.querySelector('.sorting');
let ar=[];
for (let i of div){
  const h3 = i.children[2];
  const x = h3.innerHTML.trim();
  const y = Number(x);
  i.setAttribute('data-price', y);
  ar.push(i);
}
select.onchange = sorting;
function sorting() {

  if(this.value === "Sort") {
    while(field.firstChild){
      field.removeChild(field.firstChild);
    }
    field.append(...ar)
  }
  if(this.value === "high"){
    sortElement(field, div, true);
  }
  if(this.value === "low"){
    sortElement(field, div, false);
    }
}

function sortElement(field, div, asc){
let dm, sortDiv;
dm = asc ? 1 : -1;
sortDiv = div.sort((a, b) => {
  const ax = a.getAttribute('data-price');
  const bx = b.getAttribute('data-price');
  return ax > bx ? (1*dm) : (-1*dm) ;
})
while(field.firstChild){
  field.removeChild(field.firstChild);
}
field.append(...sortDiv)
}
</script>```
