What is the best way to confirm if a Json response is empty or not?

{"PatientPastMedicalHistoryGetResult":{"PastMedicalHistory":[]}}

The PastMedicalHistory object does not contain any values. How can I verify if it is empty?

Answer №1

if (result.PatientPastMedicalHistoryGetResult.PastMedicalHistory.length == 0) {

}

This is not null, but rather an empty array.

Answer №2

In case the response is empty, give this a try:

   let result = {"PatientPastMedicalHistoryGetResult":{"PastMedicalHistory":[]}};

    for (item in result) {
        if (result[item] !== null)
            // Perform operations here
    }
