How to get key in twig?

Tried like this, but then only the first key is displayed:
{{ quote|keys|first}}

Answer 1

The attribute function will help you
https://twig.symfony.com/doc/2.x/functions/attribu...

Получить значение по ключу: attribute(myArray, myKey)
Получить ключ по номеру: myArray|keys|attribute|myKey

But it looks so perverted that it's better to write a custom function tweak and cover it with a test.
