How to deselect a nested JSON object?

Question

Currently my code is console.log("body:", body.readResults). But I do not want the value t and r. How to deselect them and get the rest?

"readResults": [
   {
       "id": "Channel1.Device1.Coil",
       "s": true,
       "r": "",
       "v": true,
       "t": 1553586722927
    }
]

Format your code, take the [tour], and then reformulate your question so that it is understandable. — Script47, Mar 26 '19 at 09:36

You can do it easily:

function cleanMyResult(result) {
    const cleanResult = Object.assign({}, result); // this will preserve your original object, but it costs some performance
    delete cleanResult.t;
    delete cleanResult.r;
    return cleanResult;
}

const cleanedResults = body.readResults.map(cleanMyResult);
console.log(cleanedResults);
