JSFiddle Misbehaving: Simple Code Fails to Perform

Facing a perplexing issue in JSFiddle, you encounter a puzzling scenario where even the simplest of codes doesn't function as expected. Despite its straightforwardness:

<code class="js">function displayMessage() {
    alert("Hello World!");
}</code>

and the corresponding HTML button:

<code class="html"><form>
    <input type="button" value="Click me!" onclick="displayMessage()" />
</form>
<p>By pressing the button above, a function will be called. The function will alert a message.</p></code>

the alert box remains conspicuously absent in JSFiddle.

Unveiling the Hidden Culprit: JavaScript Settings

Upon closer examination, the problem lies not within the code itself but in the JavaScript settings of JSFiddle. To remedy the situation, navigate to the JavaScript settings and select "No wrap - bottom of " in the "Load type" dropdown.

This setting ensures that the JavaScript code is loaded right before the closing tag, enabling it to access and manipulate the HTML elements correctly. Once this modification is made, the alert box will diligently display its message when the button is clicked, restoring harmony to your JSFiddle code.
