Shared variable in twig templates?

Question

Twig

Good afternoon everyone. I have a twig template, two more templates are included in it via include.
Is it possible to work and change with one variable in all 3 templates?
those. in the main, I create a variable, pass it to the first template, something is done with it, returned to the main one, from there it goes to the second template (with the value that turned out after the first include), processed again and the result is displayed on the main template?

Answer 1

That is, you will have a cyclic dependency of templates? It doesn't work like that. Twig allows you to define global variables if needed.
