Example of synchroneous flow

gistfile1.js

var ee = new (require('events').EventEmitter)();
var foo;

// listener function
ee.on('test', function (newValue) {
    foo = newValue;
});

// before emitting
foo = 'one';
console.log(foo);

// emitting, changing value to 'two'
ee.emit('test', 'two');
console.log(foo);

// after emitting
foo = 'three';
console.log(foo);

// console shows one two three, just synchroneous code..
