node.js function overloading

install

$ npm install overloader

overloader gives you the ability to overload your functions

to start create an overloaded environment:

var Overloader = require('overloader');

var overloaded = new Overloader();

overloaded.overload(function() {
    return 'no arguments';
});

overloaded.overload('number', function(num) {
	return 'there was a number: ' + num;
});

overloaded.overload('string', 'number', function(name, num) {
	return 'there was a number: ' + num + ' with the name ' + name;
});

declare your function and pass this and arguments to the .load() function of your environment:

function myFunction() {
	return overloaded.load(this, arguments);
}

now you can call your function as usual:

console.log(myFunction());
console.log(myFunction(5));
console.log(myFunction('Fabio Poloni', 9));

the output will be:

no arguments
there was a number: 5
there was a number: 9 with the name Fabio Poloni
