Script Preparation code:

var IDX=36, HEX='';
while (IDX--) HEX += IDX.toString(36);

function uid(len) {
  var str='', num = len || 6;
  while (num--) str += HEX[Math.random() * 36 | 0];
  return str;
}

function uid2(len = 6) {
  const  hex = '0123456789abcdefghijklmnopqrstuvwxyz';
  let id = '';
  while(len--) id += hex[Math.random() * 36 | 0];
  return id;
}

function hex() {
