jQuery like on events

[jeromejeannin]

Would be neat to have the event listeners register multiple events as it works in jQuery:
https://api.jquery.com/on/

Example:

ws.on('ready redraw', () => {
        // do x
});

Before:

ws.on('ready', () => {
        // do x
});
ws.on('redraw', () => {
        // do x
});

That would be cool indeed!
