How to convince a front-end developer to use Twig?

Question

symfony

It is planned to transfer the project to Symfony
And the question arose of choosing a template engine.
Before that, there was a negative experience using Smarty.
What arguments can help?

Answer 1

Twig is not Smarty. That's all. In general, what to convince, just put before the fact.
Seriously, just ask him to read the template developer documentation: twig.sensiolabs.org/doc/templates.html

Answer 2

You can put the barrel to the head. This argument is hard to ignore.
Your twig will consume 30-40% of the time per request. Maybe the front-end developer is just in the subject and no one needs a tweak for your json except you?)
