Javascript map array with 'fromCharCode' (character length)
<p>The following is from an interactive session in the Chrome console: </p>

<pre><code>myarray
//-&gt; [67, 65, 84]

String.fromCharCode(67)
//-&gt; "C"

String.fromCharCode(67).length
//-&gt; 1

String.fromCharCode(myarray[0])
//-&gt; "C"

String.fromCharCode(myarray[0]).length
//-&gt; 1

myarray.map(String.fromCharCode)
//-&gt; ["C", "A", "T"]

myarray.map(String.fromCharCode)[0]
//-&gt; "C"

myarray.map(String.fromCharCode)[0].length
//-&gt; 3
</code></pre>

<p>Can anyone explain why the last operation returns <code>3</code>?</p>
