This module improves on the node.js util.inherits(child, parent) method by inheriting not only instance methods and attributes, but also any class methods and attributes from the parent object.

$ npm install trustfund

####trustfund.inherits( child, parent )

Given the following Parent object:

var Parent = function Parent() {
    this.instance_attr = "life savings";
}

Parent.prototype.instance_method = function() {
    console.log('I was inherited!');
}

Parent.class_method = function() {
    console.log('All parents want to leave something to their children');
}

You can inherit all its methods and attributes using:

var inherits = require('trustfund').inherits;

var Child = function Child() {
    Child.super_.call(this);
} inherits(Child, Parent);

Now the Child object will include all the functionality of its Parent. Easy. The standard node.js util.inherits(child, parent) would have dropped Parent.class_method.

The test suite can be run by simply:

$ cd /path/to/trustfund
$ npm install -d
$ npm test
