if no filename is provided it will use stdin.
$ in the is a reference to the javascript object.

`bash
echo '{"a": {"b": [ 123 ]}}' | jq2 '$.a.b[0]' #123
echo '{"a": {"b": [ 123 ]}}' | jq2 'Math.pow($.a.b[0], 2)' #15129
echo '[" foo bar "," baz "]' | jq2 '$.map(s => s.trim()).join("")' #foo barbaz

lodash is included so this will work too

echo '[" foo bar ", " baz "]' | jq2 '$.map(_.trim).join("")' #foo barbaz

echo '{"a": 123}' > file.json
jq2 '$.a' file.json #123
