<p>Streams can be chained using the <code>map</code> method. A chained stream is also known as a <em>dependent stream</em>.</p>
<pre><code class="lang-javascript">// parent stream
var value = stream(1)

// dependent stream
var doubled = value.map(function(value) {
    return value * 2
})

console.log(doubled()) // logs 2
