Hands-On Node Event Emitter Exercise 1

eventemitter.js

var EventEmitter = require('events').EventEmitter;
var util = require('util');

// Here is the Ticker constructor
var Ticker = function() { // This is a pseudo-class }

util.inherits(Ticker, EventEmitter);

// Emit tick on the tick event
Ticker.prototype.tick = function() {
	this.emit('tick event', 'tick');
}

var ticker = new Ticker();

function tick() {
	setTimeout(function() {
		console.log('tick');
		tick();
	}, 1000);
}

ticker.on('tick event', tick);

ticker.tick();

Hello Josh

var Ticker = function() { // This is a pseudo-class }

does not work, to fix it I moved the closing brace to the next line:

var Ticker = function() { // This is a pseudo-class 
}

Can you comment on this?
