The {% verbatim %} tag marks entire sections as being raw text that should not be parsed.
{% verbatim %}<p>Hello, {{ name }}</p>{% endverbatim %}
The above will render in the browser exactly as:
<p>Hello, {{ name }}</p>
For example, AngularJS uses the same templating syntax so you can decide which variables to use for each.
<p>Hello {{ name }}, this is parsed by Twig</p>
{% verbatim %}
<p>Hello {{ name }}, this is parsed by AngularJS</p>
{% endverbatim %}
