keyboardevent-key-polyfill

Polyfill for KeyboardEvent.prototype.key.

NOTE: All major browsers now support KeyboardEvent.prototype.key. Firefox already shipped with this for a while; recent versions of Edge, Chrome, and Safari also now have shipped support. This will still enable KeyboardEvent.prototype.key in environments where it may not yet be available.

Example

Say goodbye to this:

document.addEventListener('keydown', function (e) {
  console.log('Code of key pressed:', e.which || e.keyCode);  // 39
});

And hello to this:

  console.log('Name of key pressed:', e.key);  // ArrowRight
});
