Challenge 1 / 2

Check out the following config:

# config/packages/twig.yaml
twig:
    globals:
        answer_to_everything: 42

How could we override the answer_to_everything config value to be 21 in the dev environment only?

Both B and C work.

Add a when@dev section at the bottom:

# config/packages/twig.yaml
twig:
    globals:
        answer_to_everything: 42

when@dev:
    twig:
        globals:
            answer_to_everything: 21

Create a new config/packages/dev/twig.yaml file with:

# config/packages/dev/twig.yaml
twig:
    globals:
        answer_to_everything: 21
