IE11 Javascript: let [array] of object.entries "SCRIPT1010: Expected identifier" error

In this block of code, I'm finding the "SCRIPT1010: Expected Identifier" Error on the first line in IE11. This works perfectly in all other major browsers.

for (let [key, value] of Object.entries(CompanySettings)) {
 if (value == true) {    
   document.getElementById(key).removeAttribute("checked");
 }
 if (value == false) {
  document.getElementById(key).setAttribute("checked", "no");
 }
}

I'm assuming this is because it's an ES6 feature that's not available in IE, but I'm wondering if there's an plain old JS alternative I could use to the let.. of.. that works in IE11. I'm not really interested in adding an extra library just to get this block running.

You could take a for ... in statement and iterate the keys.

for (var key in CompanySettings) {
    if (CompanySettings[key]) { // assuming true or false values
        document.getElementById(key).removeAttribute("checked");
    } else {
        document.getElementById(key).setAttribute("checked", "no");
    }
}

Maybe you need another check for not own properties

for (var key in CompanySettings) {
    if (!CompanySettings.hasOwnProperty(key)) continue;
    if (CompanySettings[key]) { // assuming true or false values
        document.getElementById(key).removeAttribute("checked");
    } else {
        document.getElementById(key).setAttribute("checked", "no");
    }
}
