create-error

create-error.js
===============

A simple helper for creating subclassed errors in Javascript.


Use:

``bash
$ npm install create-error
$ bower install create-error
`

`js
var createError = require('create-error');
var MyCustomError = createError('MyCustomError');
var SubCustomError = createError(MyCustomError, 'CoolSubError', {messages: []});

var sub = new SubCustomError('My Message');

sub instanceof SubCustomError // true
sub instanceof MyCustomError // true
sub instanceof Error // true

assert.deepEqual(sub.messages, []) // true
`

Creates a new error by specifying the name of the error to be created,
taking an optional hash of properties to be attached to the error class
upon creation.

Create a new error by specifying the Target error class we wish to inherit from,
along with an optional name and properties for the error. If the name is omitted,
it will have the same name as the parent error.

In the browser, the function will be assigned to window.createError,
and createError.noConflict() will restore the original window.createError`
if overwritten.
