Match variable to JSON content and return data
<p>I have a variable that contains a country name.</p>

<pre><code>var country = 'belgium';
</code></pre>

<p>I have a JS data structure:</p>

<pre><code>var countryCoords = {
  argentina: '56 100',
  belgium: '100 200'
}
</code></pre>

<p>How do I get the co-ordinates for Belgium?</p>
