A JSON Query Language CLI tool. A little like the venerable jq a little not, has different selection (or 'query') syntax.

Basically you pass in JSON to select specific JSON from whatever data.
Feels a little weird to me at first, but might actually be easier for intermediate/advanced use cases then the mind-bending mess jq sometimes turns into for me

(or rather, the constant trial and error with jiq that it turns into)
