title: how to compare two string and highlight changes?
body: <p>I have two strings.</p>
  
  <pre><code>stringV1 = "123456";
  stringV2 = "102300456";
  </code></pre>
  
  <p>First I need to compare them.</p>
  
  <p>If <code>stringV2</code> has some changes, this new text should be highlighted like this:</p>
  
  <pre><code>"1'0'23'00'456"
  </code></pre>
