What are twig functions?

Twig functions are reusable functions that can be called from within Twig templates to perform a specific task or return a value.

They are typically used to keep template logic simple and readable by moving more complex or reusable operations into functions. A Twig function can accept parameters, perform some processing, and return a result that can then be used in the template.

For example, you can use {{ store_name() }} in twig to output your store's name.
