Node version affecting event listener callbacks

[arjasco]

So i've just experienced what could be a bug or i've misunderstood something. I'm not a fan of TS or i would dig around the code myself.

I have been running Node 6.4.0 and found that i needed a second parameter in my event listeners callback to retrieve the event data, the first parameter became the channel name. However using node 4.6.0 i only require one parameter for the data.

Example:

Node 4.6.0

this.socket.private('Channel').listen('Event', payload => {
  this.update(payload.data)
})

Node 6.4.0

this.socket.private('Channel').listen('Event', (channel, payload) => {
  this.update(payload.data)
})

I haven't checked against other node versions yet. Not sure if this is something to do with webpack / ES6 complier maybe?
