How to print two values from the response (array of JSON objects)

I have a test in Karate where the response is an array of JSON objects, all of them include a key called id. and name. I need to print only id -> name from the entire response

I can print a single values like this

• def id = $response.data[*].id
• def name = $response.data[*].name

But not sure how to print both values together

It is better to just loop over the array. Note that print also gives you the option to have multiple arguments like karate.log() below:

* response.data.forEach(x => karate.log('id:', x.id, 'name:', x.name)

You should be using Karate to do assertions, not print :)

Another way to approach the problem is to create a new array:

* def temp = response.data.map(x => `${x.id} - ${x.name}`)
* print temp
