## 1. Which syntax is used to display a variable in a Twig template?

**Answer**

The {{ }} (double curly braces) syntax is used to display a variable's content in Twig. This syntax automatically performs HTML escaping to prevent XSS attacks. For control structures, use {% %}, and for comments use {# #}.

## 2. How to write a comment in a Twig template?

**Answer**

Twig comments use the {# #} syntax. These comments are not rendered in the final HTML output, unlike standard HTML comments. This allows adding developer notes without exposing information to users.

## 3. What is the purpose of the {% extends %} tag in Twig?

**Answer**

The extends tag enables template inheritance by defining a parent template. The child template inherits the entire parent structure and can override defined blocks. This promotes reusability and maintains a consistent structure across the site.
