Validating object keys

I am dealing with an array of objects and I need to find a way to pass multiple keys in the function checkArray to validate these keys within each object.

var test = [
  {
    // Object details here...
  },
  {
    // Another object details here...
  }
];

function isKeyInObject(obj, key) {
  var res = Object.keys(obj).some(v => v == key);
  return res;
}

const checkArray = (test, ...keys) => {
  let valid = true;

  test.map(item => {
    keys.forEach(key => {
      if (!isKeyInObject(item, key)) valid = false;
    });
  });

  return valid;
};

console.log(checkArray(test, 'VAT', 'destination', 'insured_tin'));

Is there a way for me to pass a list of keys instead of just one key for validation? Currently, I can only pass one key at a time. Ideally, I'd like to use something like 

checkArray(test, 'VAT', 'destination', 'insured_tin');

Answer №1

You can easily accomplish this by utilizing the every method of Array

var sampleData = [
  {
    date_issued: '2018-05-25',
    transaction_type: 'IMPORT',
    policy_number: '061/100/001052/2018',
    open_cover: false,
    endorsement_number: '',
    icc: 'ICC-A',
    insured_name: 'SAYONA STEEL LTD',
    insured_email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fc919590919d8ebc9b919d9590d29f9391">[email protected]</a>',
    insured_tin: '103 286 883',
    intermediary_name: 'MILMAR',
    intermediary_tin: '100-714-078',
    goods_category: 'Mineral Products',
    country_of_origin: 'HK',
    destination: 'Mwanza Region',
    conveyance: 'SEA',
    financier: '',
    currency_code: 'USD',
    exchange_rate_used: '2262.37',
    sum_insured: '23302411',
    premium: '33935.55',
    VAT: '5176.609322',
    unit_of_measure: 'UNITS',
    quantity: '800',
    cover_start_date: '2018-05-15'
  },
  {
    date_issued: '2018-05-25',
    transaction_type: 'IMPORT',
    policy_number: '061/100/001051/2018',
    open_cover: false,
    endorsement_number: '',
    icc: 'ICC-A',
    insured_name: 'URHOME COMPANY LTD',
    insured_email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="dbb6b2b7b6baa99bbcb6bab2b7f5b8b4b6">[email protected]</a>',
    insured_tin: '132-209-898',
    intermediary_name: 'MILMAR',
    intermediary_tin: '100-714-078',
    goods_category: 'Base Metals And Articles Of Base Metal',
    country_of_origin: 'CN',
    destination: 'Dar es Salaam Region',
    conveyance: 'SEA',
    financier: '',
    currency_code: 'USD',
    exchange_rate_used: '2262.37',
    sum_insured: '54941202.98',
    premium: '58821.62',
    VAT: '8972.789492',
    unit_of_measure: 'UNITS',
    quantity: '2792',
    cover_start_date: '2018-05-15'
  }
];

const checkKeysExist = (sampleData, keys) => {
  return sampleData.every(item => keys.every(key => item.hasOwnProperty(key)));
};

console.log(checkKeysExist(sampleData, ['VAT', 'currency_code']));
console.log(checkKeysExist(sampleData, ['VAT', 'unknown']));

To check if an object has specific keys in JavaScript, you can easily use the hasOwnProperty() method.

var test = [
  {
    date_issued: '2018-05-25',
    transaction_type: 'IMPORT',
    policy_number: '061/100/001052/2018',
    open_cover: false,
    endorsement_number: '',
    icc: 'ICC-A',
    insured_name: 'SAYONA STEEL LTD',
    insured_email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="563b3f3a3b372416313b373f3a7835393b">[email protected]</a>',
    insured_tin: '103 286 883',
    intermediary_name: 'MILMAR',
    intermediary_tin: '100-714-078',
    goods_category: 'Mineral Products',
    country_of_origin: 'HK',
    destination: 'Mwanza Region',
    conveyance: 'SEA',
    financier: '',
    currency_code: 'USD',
    exchange_rate_used: '2262.37',
    sum_insured: '23302411',
    premium: '33935.55',
    VAT: '5176.609322',
    unit_of_measure: 'UNITS',
    quantity: '800',
    cover_start_date: '2018-05-15'
  },
  {
    date_issued: '2018-05-25',
    transaction_type: 'IMPORT',
    policy_number: '061/100/001051/2018',
    open_cover: false,
    endorsement_number: '',
    icc: 'ICC-A',
    insured_name: 'URHOME COMPANY LTD',
    insured_email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7c111510111d0e3c1b111d1510521f1311">[email protected]</a>',
    insured_tin: '132-209-898',
    intermediary_name: 'MILMAR',
    intermediary_tin: '100-714-078',
    goods_category: 'Base Metals And Articles Of Base Metal',
    country_of_origin: 'CN',
    destination: 'Dar es Salaam Region',
    conveyance: 'SEA',
    financier: '',
    currency_code: 'USD',
    exchange_rate_used: '2262.37',
    sum_insured: '54941202.98',
    premium: '58821.62',
    VAT: '8972.789492',
    unit_of_measure: 'UNITS',
    quantity: '2792',
    cover_start_date: '2018-05-15'
  }
];

const checkArray = (test, keys) => {
  let valid = true;
  test.map(object => {
    keys.map(key => {
        if(!object.hasOwnProperty(key)) {
            valid = false;
        }
    });
  });

  return valid;
};

console.log(checkArray(test,['VAT','intermediary_name']));
console.log(checkArray(test,['VAT','intermediary']));
