On: Vue 3 drops IE11 support plan

[seumars]

There are lot of snippets out there, the most common way would be to target the window.navigator.userAgent, something like:

  function isIE() {
    return /Trident\/|MSIE/.test(window.navigator.userAgent);
  }

Keep in mind that the code has to compile for checks to work. Eg a ‘let’ in the same script block will break the isIE check too and it’s easy to miss that someone broke it. How often does the ie11 code get tested on ie11..

Best to keep the IE 11 warning code in a separate (nomodule?) script file
