You can also create a closure over the variables you need to reference.

This is done by creating your event listener function within the
lexical scope that contains your referenced variables:

function doStuff() {
  var allTheVariablesYouCareAbout = stuff;

  function handler(e) {
    var stuff;
    var with;
    var do = stuff + with + allTheVariablesYouCareAbout;
  }
  yourFaviconImg.addEventListener('error', handler, true);
}
