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

<hr>

Say goodbye to this:

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

And hello to this:

document.addEventListener('keydown', function (e) {
  console.log('Name of key pressed:', e.key);  // ArrowRight
});

Usage

Just drop the script on your page and call the polyfill method.

<script src="index.js"></script>
<script>keyboardeventKeyPolyfill.polyfill();</script>

If you're using AMD:

Then require the CommonJS module for use with Browserify/webpack:
