'Switch statement' in twig is not available so what is alternate of 'switch' in twig instead 'if statement'.

@ravi kant – TWIG isn't really meant to contain a lot of complex logic. All of that really should go into preprocess/extra fields/field formatters. That is probably the primary reason why switch statements are not a thing in core TWIG.

Thank you @philip_stier

I try to search modules for "extra fields" and "field formatters".
Can you suggest modules that are good to use?
