popo

Simple way to implement polymorphism in javascript

Install

Install with npm:

npm install --save popo

Usage

There is only possible overload function by arguments number

var popo = require('popo');

var sayHello = popo({
    0: function () {
        return 'Hello Anonymous!';
    },
    1: function (name) {
        return 'Hello ' + name + '!';
    }
}, function otherWay () {
    return 'Do I need to say Hello?';
});

sayHello(); // 'Hello Anonymous!';
sayHello('Haruki'); // 'Hello Haruki!';
sayHello('Haruki', 'Murakami'); // 'Do I need to say Hello?';

TODO

• overload by type
• add browser support
• better implementation of default function
