arrays - Instead of null, send a message for no value in Javascript

Solution:

Try out the below code this should fix your bug if not then let me know. I will try another method of rendering an empty statement.

const emptyStatement = () => {
  const empty_Statement = "You have no wishlist item.";
  const resetWishlist = empty_Statement;
  return setWishlist([empty_Statement]);

  document.getElementById("oasis-wishlist").innerHTML = emptyStatement();
};

Answer

Solution:

Ok. so here you can add a condition while fetching Wishlist products. ifproductarr.length==0 then set the inner HTML of Wishlist to<h1> Wishlist empty </h1> else if there is data then print the data as per your choice. i can't actually provide the code because it will alter whole of your code. apply the above logic accordingly and that will fix your code.

fetch(url).then((res)=>
{
if(res.data.length)
    setwihslist([res.data])
else
    wishlist.innerHTML="emptywishlist";
}
