Microsoft retired IE in 2022​

Outside of intranet apps and specialized industries, IE has been end-of-life since June 15, 2022. Detecting it is usually a signal to gracefully refuse to render rather than feature-flag.

import { isIE } from 'get-browser';

if (isIE()) {
  window.location.replace('/unsupported');
}
