Usage

import { Key } from 'w3c-keys';

// To dispatch Events.
let evt = new KeyboardEvent('keydown', {
    key: Key.Space
});
document.body.dispatchEvent(evt);

// To check event keys.
document.body.on('keydown', (e) => {
    if(e.key === Key.Backspace) {
        // Do some shiz...
    }
});

Why not use evt.which keyCodes ?

• evt.which keycodes are a deprecated standard.
• Ability to create synthetic key events is not possible with evt.which.
