Verify if the keys are present within the object and also confirm if they contain a value

Question

Verify if the keys are present within the object and also confirm if they contain a value

How can we verify keys and compare them to the data object? If one or more keys from the keys array do not exist in the object data, or if a key exists but its value is empty, null, or undefined, then return false; otherwise, return true.

For example, if the keys include 'summary' and it exists in the object data but the value is empty, the result should be false;

I have attempted using Object.keys and includes but haven't been able to figure it out. Perhaps someone has a solution. Thank you.

#currentCode

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

Thank you.

#keys

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

#sample object data

    "dealDispositionType": "A",

To validate if all keys in an array are present and not empty in a given object, you can utilize the every() method along with hasOwnProperty and additional checks for empty strings.

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

Your code has been successfully optimized.

const data =  Object.entries(jsonObject).map(([k, v]) => {
   return keys.includes(k) ? v ? true : false : false;
})

'summary',
'targetRecdate',
'majorPositiveAttributes',
'generalRealEstateConcernsorChallenges',

const object = {
    "dealDispositionType": "A",
    "majorPositiveAttributes": "a",

    "pharmacyRestrictionDate": null,
    "targetRecdate": "2022-10-20",
    "isLandLordConsent": false,
    "summary": "test"
}

let array = [];

const output = Object.entries(object).map(([key, value]) => {
    if (keys.includes(key)) {
        if ((value !== '') && (value !== 'undefined') && (value !== 'null')) {
            return true;

            return false;
        }

const finalValue = output.includes(true);

console.log(finalValue)

To verify the presence of all keys in the data variable, I suggest utilizing the .every method.

Furthermore, by using non-strict !=, you can determine if a certain key does not contain either null or undefined.

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 check = (obj, keys) => keys.every((key) =>  
    key in obj && obj[key] != undefined);

console.log(check(data, keys));
