Question

I have a conditional when I execute this On IE v11 event the first block is true is not execute because I have error on my second one, My question is how I can void this behavior I Mean in this case I want to show the alert and don't execute nothing more if I am IE v11.

if (window.navigator.userAgent.indexOf('Trident/') > 0) {
        alert('this browser is not supported');
         return
    } else {
        var se = `some here`; // <- this is not supported on EI v11
        console.log('here',se);
}

Well, its a dirty solution and I highly do not recommend to use it. But you can use eval like that:

if (window.navigator.userAgent.indexOf('Trident/') > 0) {
  alert('this browser is not supported');
  return;
} else {
  eval('var se = `some here`'); // <- this is not supported on EI v11
  console.log('here',se);
}
