Regex expressions

You can now use regex expressions in your templates.

Being possible does not mean you should use them. You’d betterkeep the regex on the component side and not in the template.

If the interpolation is meant to evaluate a JavaScript expression, some of them were not supported yet. The regex expression is part of them.

Exercise

<div class="website-info">
  <p>
    Domain: {{ websiteUrl.match(/^https?:\/\/([^\/]+)/)?.[1] || 'Invalid URL' }}
  </p>
</div>
