konamiCode(() => {
  /* do stuff */
});

If you want to remove the listener, call the remove() function on the returned object, or on this in the callback function:

const kc = konamiCode(() => {
  /* do stuff */
});
kc.remove();

// - or -

konamiCode(function() {
  /* do stuff */
  this.remove();
});
