Absolutely tiny emitter.

e.js

function e(m,i,t){return m.map(function(l){return l(i,m)})}

example.js

var someObj = {
    onSomeEvent: []
};

someObj.onSomeEvent.push(function (message) {
    console.log('Message was', message, this.suffix);
});

e(someObj.onSomeEvent, ['A MESSAGE'], {
    suffix: '[This is from the scope!]'
});

// Result: Message was A MESSAGE [This is from the scope!]
