### Formatting output

lists the following nu snippet as involved but equivalent:

'{"name": "Alice", "age": 30}'
| from json
| items { |key, value| ["Name" $value] | str join ": " }
| str join ", "
# => Name: Alice, Name: 30

For equivalence, Name: 30 should be Age: 30.

It should be

'{"name": "Alice", "age": 30}'
| from json
| items { |key, value| [($key | str capitalize) $value] | str join ": " }
| str join ", "

Or

'{"name": "Alice", "age": 30}'
| from json
| items {|key, value|
  ($key | str capitalize) ++ ": " ++ ($value | into string)
} | str join ", "

Ok, so I have looked at the original jq query, and the equivalent of that is actually this:

'{"name": "Alice", "age": 30}' | from json
| format pattern "Name: {name}, Age: {age}"

The jq syntax doesn't appear to work either.

❯ ^echo '{"name": "Alice", "age": 30}' | jq -r "Name: \(.name), Age: \(.age)"
jq: error: syntax error, unexpected ':', expecting end of file at <top-level>, line 1, column 5:
    Name: (.name), Age: (.age)
        ^
jq: 1 compile error

I'm guessing there are several changes since I wrote it.
