Generate #2 hash 0-99 from a string in javascript

Add hash prefix to href description (innerHtml) that are inside a specific div
=================================================================
// script.js
function addHashLabels() {
  const divprobesrv = document.getElementById('probeserver');
  //const links = document.getElementsByTagName('a');
  const links = divprobesrv.getElementsByTagName('a');
  const hashRange = 99 - 1 + 1; // 01 to 99

  for (let i = 0; i < links.length; i++) {
    const url = links[i].getAttribute('href');
    const hash = getHash(url);

    // Generate prefix based on hash number
    const prefixletter=links[i].innerHTML.charAt(0);
    //console.log("InnetHTML="+prefixletter+ " , innerHTML="+links[i].innerHTML)
    const prefix = prefixletter+('0' + (hash % hashRange + 1)).slice(-2);

    // Add prefix to link description
    links[i].innerHTML = prefix + ': ' + links[i].innerHTML;
  }
};

// Function to generate hash from URL
function getHash(url) {
  let hash = 0;
  for (let i = 0; i < url.length; i++) {
    hash = ((hash << 5) - hash) + url.charCodeAt(i);
    hash = hash & hash; // Convert to 32bit integer
  }
  return Math.abs(hash);
