To see the value of a variable,
use the 11ty log filter which calls console.log.
This writes to the terminal window where the Eleventy server is running,
not to the DevTools console.
For example:
{% set temp = myVariable | log %}

To render the content of an array or object within a page,
use the Nunjucks dump filter which calls JSON.stringify.
For example:
{{ myVariable | dump }}
