derive

derive 
======

A utility to either derive from multiple super-constructors,
or inherit from one super-constructor.

You shouldn't rely on getters or setters with side effects
(like the Array's length property) when deriving from native types.
(You probably shouldn't derive or inherit from native types anyway)

Also, the instanceof operator will not work as expected,
because it checks if a prototype in the chain is equal to
the prototype of the object it's being checked against -
which means it will return false for everything you've derived from.

That's why it's called derive, not inherit.

Install with npm

``sh
$ npm install derive
`

Install with bower

`shell
$ bower install derive

Deriving from multiple super-constructors:

`javascript
// Your constructor function
function Example() {
// Don't forget to call the
// super's constructors
EventEmitter.call( this )
Array.call( this )
}

// Your prototype
Example.prototype = {
constructor: Example,
get bla() { return 1 },
method: function() {
// ...
}
}

derive( Example, EventEmitter, Array )
`

Inheriting from a super-constructor:

`javascript
function Example() {
Emitter.call( this )
}

Example.prototype = {
constructor: Example,
set setter( value ) {},
method: function noop() {
// ...
}
}

derive.inherit( Example, Emitter )
