Javascript - Only in IE it gives me "Expected identifier"

Question

I've tested the following code on every browser, and only Internet explorer says its expect an identifier. I've been through many sites but i cant find the answer by myself.

    var ref = firebase.database().ref("products");
ref.once("value",  function(snapshot)  {

   let profiles2 = []
      snapshot.forEach( function(profile) {
       let {url,mobile2} = profile.val();
        profiles2.push({url,mobile2}) 
})
})

Im glad for every answer!

What happens if you directly do profiles2.push(profile.val();}) — Renaud Tarnec, Apr 18 '18 at 21:12

It might be due to IE not supporting ES6 fully. You can use babel to compile your code to ES5 to make sure it is supported by all browsers.

What browsers currently support JavaScript's 'let' keyword?
