title: Find difference between two strings in JavaScript
body: <p>I need to find difference between two strings.</p>
  <pre><code>const string1 = 'lebronjames';
  const string2 = 'lebronnjames';
  </code></pre>
  <p>The expected output is to find the extra <code>n</code> and log it to the console.</p>
