Custom JS work in Google Chrome but not in IE11

[Steve]

Hello,
I have a piece of code:

function rozjedTo() {

function RemoveAccents(str) {
  var accents = ('ÀÁÂÃÄÅĄĀāàáâãäåąßÒÓÔÕÕÖØŐòóôőõöøĎďDŽdžÈÉÊËĘĚěèéêëęðÇçČčĆćÐÌÍÎÏĪìíîïīÙÚÛÜŰŮùűúûůüĽĹŁľĺłÑŇŃňñńŔŕŠŚŞšśşŘřŤťŸÝÿýŽŻŹžżźđĢĞģğ');
var accentsOut = ("AAAAAAAAaaaaaaaasOOOOOOOOoooooooDdDZdzEEEEEEeeeeeeeCcCcCcDIIIIIiiiiiUUUUUUuuuuůuLLLlllNNNnnnRrSSSsssRrTtYYyyZZZzzzdGGgg");
  str = (str.split(''));
  var strLen = str.length;
  var i, x;
  for (i = 0; i < strLen; i++) {
    if ((x = accents.indexOf(str[i])) != -1) {
      str[i] = accentsOut[x];
    }
  }
  return str.join('');

}

let stat = getFieldValue("Stat");
let vysledekStat = stat.toUpperCase();
let trimStat = vysledekStat.trim();

let sapJmeno = getFieldValue("Jmeno");
let sapPrijmeni = getFieldValue("Prijmeni");
let sapUsername = sapPrijmeni.substring(0, 5) + sapJmeno.substring(0, 3);
let vysledek = sapUsername.toUpperCase();
let rozdilovka = ("P"+ vysledekStat + "-" + RemoveAccents(vysledek));
setFieldValue("sapUsername",rozdilovka);
    
}

It works great in Google Chrome and MS Edge, but not in IE11.
If I open development tools – console in GChrome – it shows no errors.
If I open IE development tools – console – it shows error depicted in the attachment.
The function is linked to a button “onclick” in “tabs” section.
Thank you in advance.

My guess is that Internet Explorer is running in compatibility mode and does not support let. Change it to var and you should be good to go.

You’re a magician Alex, thank you, it works perfectly. I hope it will help other people someday.
