Am I correct in understanding that this can only manipulate (get or set values) from a JSON path? That is, is it not a replacement for jq?

For example, I frequently use jq for queries like this:

    jq '.data | map(select(.age <= 25))' input.json

Or this:

    jq '.data | map(.country) | sort[]' input.json | uniq -c

Is it possible to do something similar with this tool?

This is not a slight at jj. Even if it's more limited than jq, it's still of great value if it means it's faster or more ergonomic for a subset of cases. I'm just trying to understand how it fits in my toolbox.
