function-emitter

A tiny prototype to set on a funciton to make it work as an event emitter.

Usage

var functionEmitter = require('function-emitter');
 
var doThing = function(a,b){
    return a + b;
};
 
Object.setPrototypeOf(doThing, functionEmitter);
 
doThing(2, 4); // -> 6
 
doThing.on('foo', function(foo){
 
});
 
doThing.emit('foo', 'bar'); // Handled above.
