<p>Combine data sets and create shallow copies of objects with `merge`</p>

<h3>Using `merge`</h3>

```

YUI().use('node', 'dump', function(Y) {

// This method is in the core of the library, so we don't have to use() any

// additional modules to access it. However, this example requires 'node' and 'dump'.

```

<h3>Merging hash tables</h3>

<p>When the "Merge" button is clicked, we merge three object literals in the form

of hash tables. Note the key values in later parameters override those in

previous parameters.</p>

<h3>Creating Shallow Copies</h3>

<p>When the "Copy" button is clicked, we create use merge on a single

object in order to create a shallow clone. The code illustrates the

fact that object properties of the result object are shared with

the input object.</p>
