A port of jQuery.extend that actually works on node.js

None of the existing ones on npm really work therefore I ported it myself.

To install this module in your current working directory (which should already contain a package.json), run

npm install node.extend

You can additionally just list the module in your package.json and run npm install.

Then, require this package where you need it:

var extend = require('node.extend');

The syntax for merging two objects is as follows:

var destObject = extend({}, sourceObject);
// Where sourceObject is the object whose properties will be copied into another.
// NOTE: In this situation, this is not a deep merge. See below on how to handle a deep merge.

For information about how the clone works internally, view source in lib/extend.js or checkout the doc from jQuery

In order to force a deep merge, when extending an object, you must pass boolean true as the first argument to extend:

var destObject = extend(true, {}, sourceObject);
// Where sourceObject is the object whose properties will be copied into another.

See this article for more information about the need for deep merges in JavaScript.
