<p dir="auto">One of the help links that's suppose to direct to Mozilla documentation on String.charCodeAt() instead points to <a href="https://www.freecodecamp.com/challenges/undefined" rel="nofollow">https://www.freecodecamp.com/challenges/undefined</a></p>

Please describe how to reproduce this issue, and include links to screenshots if possible.</p>
<p dir="auto">My code:</p>
<div class="highlight highlight-source-js notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="
function rot13(str) { // LBH QVQ VG!

  return str;
}

// Change the inputs below to test
rot13(&quot;SERR PBQR PNZC&quot;);
"><pre class="notranslate"><span class="pl-k">function</span> <span class="pl-en">rot13</span><span class="pl-kos">(</span><span class="pl-s1">str</span><span class="pl-kos">)</span> <span class="pl-kos">{</span> <span class="pl-c">// LBH QVQ VG!</span>

  <span class="pl-k">return</span> <span class="pl-s1">str</span><span class="pl-kos">;</span>
<span class="pl-kos">}</span>

<span class="pl-c">// Change the inputs below to test</span>
<span class="pl-en">rot13</span><span class="pl-kos">(</span><span class="pl-s">"SERR PBQR PNZC"</span><span class="pl-kos">)</span><span class="pl-kos">;</span></pre></div>
<p dir="auto">The issue is not within the code, actually... It is on the challenge's explanation page.<br>
It seems that the link to "String.charCodeAt()" is broken.</p>
<p dir="auto">I think it should be the following:<br>
