Answer 1

You could do it easily using map() as follows -

 const myArr = [{ "Key": "ProducePRINKA0370001", "Record": { "docType": "Produce", "PRODUCEID": "PRINKA0370001" } }, { "Key": "ProducePRINKA0370038", "Record": { "docType": "Produce", "PRODUCEID": "PRINKA0370038" } }, { "Key": "ProducePRINKA0370050", "Record": { "docType": "Produce", "PRODUCEID": "PRINKA0370050" } } ]; const modifiedArr = myArr.map((el) => { return el.Record; }) console.log(modifiedArr)

The above code just maps over your initial array ( myArr in this case) and just returns the Record part from each of the objects in the myArr array. Finally what map() built-in function of JS does is that it returns an array consisting of all elements which you return in the function provided inside map .

Answer 2

You can use map function to get the result you want.

var result = source.map((item) => item["Record"]);

console.log(result);

Here source is the array of the source array.
