Karate – Match two dynamic responses

For a simpler example that can give you a better understanding of the concept, especially karate.map() which can even be used on nested JSON structures, see here: https://stackoverflow.com/a/65036047/143475

And also read the docs: https://github.com/intuit/karate#json-transforms
