check if keys exist in object and if it has value

October 6, 2022

How do we check the keys and compare it to the data object , if one or more keys from the keys array does not exist in object data or if it exist or key exists and the key value has no value or null or undefined then return false else return true.

For example keys has a key summary and it exists on object data but the value is empty so it should return false;

I’ve tried Object.keys and used includes but cant seem to work it out, maybe someone has an idea. Thanks.

#currentCode

 const sample =  Object.entries(sampleOject).some((value) => {
          return keys.includes(value[0]) ? false : (value[1] === null || value[1] === "");
      })

Thanks.

#keys

const keys =  [
    'summary',
    'targetRecdate',
    'majorPositiveAttributes',
    'generalRealEstateConcernsorChallenges',
    'terminationPayment',
    'effectiveDate',
    'brokerCommission',
    'brokerRebate',
    'netEffectiveBrokerCommission']

#sample object data

{
    "dealDispositionType": "A",
    "majorPositiveAttributes": "a",
    "terminationPayment": "31",
    "netEffectiveBrokerCommission": -12189,
    "brokerCommission": "123",
    "brokerRebate": "12312",
    "isPharmacyRestriction": 0,
    "periodOfRestriction": null,
    "pharmacyRestrictionDate": null,
    "targetRecdate": "2022-10-20",
    "isLandLordConsent": false,
    "summary: ""
}

>Solution :

You could use every() with hasOwnProperty and additional checks for empty strings etc

const result = keys.every(key => {
    return data.hasOwnProperty(key) && data[key] !== ''
}, {});

const keys =  [
    'summary',
    'targetRecdate',
    'majorPositiveAttributes',
    'generalRealEstateConcernsorChallenges',
    'terminationPayment',
    'effectiveDate',
    'brokerCommission',
    'brokerRebate',
    'netEffectiveBrokerCommission'
];

const data = {
    "dealDispositionType": "A",
    "majorPositiveAttributes": "a",
    "terminationPayment": "31",
    "netEffectiveBrokerCommission": -12189,
    "brokerCommission": "123",
    "brokerRebate": "12312",
    "isPharmacyRestriction": 0,
    "periodOfRestriction": null,
    "pharmacyRestrictionDate": null,
    "targetRecdate": "2022-10-20",
    "isLandLordConsent": false,
    "summary": ""
};

const result = keys.every(key => {
    return data.hasOwnProperty(key) && data[key] !== ''
}, {});

console.log(result); // False
