Use of fat arrow functions in JSFiddle with TypeScript
<p>I've had some snippets on JSFiddle for some blog posts using TypeScript, but some of them have stopped working.</p>

<p>Specifically it's when I use the fat arrow notation for function definitions.
It have been working before, so maybe I need to set some options on JSFiddle?</p>

<p>Here is a simple example: <a href="https://jsfiddle.net/CaveOfCode/3wdme693/1/" rel="nofollow">https://jsfiddle.net/CaveOfCode/3wdme693/1/</a>
With the following snippet:</p>

<pre><code>const fatArrow = () =&gt; console.log("fatArrow");
fatArrow();
const functionKeyword = function() { console.log("functionKeyword"); };
functionKeyword();
</code></pre>

<p>The <code>fatArrow</code> throws the error.</p>

<pre><code>VM111:2 Uncaught SyntaxError: Unexpected identifier
</code></pre>
