I have an Array called transactions. The elements in the Array are a collection of objects. The objects in turn have nested elements.
How do I capture the nested elements in the objects, in particular, the value of the element called transPayersNumber?
Find below the structure of my Array:
transactions[
{numberOfMobileTransactions: 200, day: Wednesday,
phoneNumbers: [{ _id: 60bdf6c18fd22aac8c4b35f2,
transPayersNumber: '0705667966',
transCounty: 'Kiambo'
}]
},
{numberOfMobileTransactions: 120,day: Tuesday,
phoneNumbers: [{ _id: 60bdf6c1654622aac8c4b35f2,
transPayersNumber: '0747897933',
transCounty: 'Kiambo'
},
{ _id: 60bdf6sdtd4622aac8c4b35f2,
transPayersNumber: '0747845631',
transCounty: 'Nairobi'
}]
}
]
How do I access the value of the element in the nested Object transactions.phoneNumbers.transPayersNumber?
In a failed attempt to access the value of the transPayersNumber element I tried a variety of codes but the code below is as far as I have gotten without any error messages:
transactions.forEach(transactions => {
console.log("Transactions: " +transactions.day + " by: " +transactions.phoneNumbers )
});
The code above yeilds:
Transactions: Wednesday by: {
_id: 60bdf6c18fd22aac8c4b35f2,
transPayersNumber: '0705667966',
transCounty: 'Kiambo'
},
Transactions: Tuesday by: {
_id: 60bdf6c18fd22aac8c4b35f2,
transPayersNumber: '0705667966',
transCounty: 'Kiambo'
},
Transactions: Tuesday by: {
_id: 60bdf6c18fd22aac8c4b35f2,
transPayersNumber: '0705667966',
transCounty: 'Kiambo'
}
My desired output would be something similar to the below:
Transactions: Wednesday by: 0705667966
Transactions: Tuesday by: 0747897933, 0747845631
This should work:
const transactions = [
{
"numberOfMobileTransactions": 200,
"day": "Wednesday",
"phoneNumbers": [
{
"_id": "60 bdf6c18fd22aac8c4b35f2",
"transPayersNumber": "0705667966",
"transCounty": "Kiambo"
}
]
},
{
"numberOfMobileTransactions": 120,
"day": "Tuesday",
"phoneNumbers": [
{
"_id": "60 bdf6c1654622aac8c4b35f2",
"transPayersNumber": "0747897933",
"transCounty": "Kiambo"
},
{
"_id": "60 bdf6sdtd4622aac8c4b35f2",
"transPayersNumber": "0747845631",
"transCounty": "Nairobi"
}
]
}
];
const transPayersNumbersArray = [];
transactions.map(eachObj => {
const phoneNumbers = eachObj.phoneNumbers;
if (phoneNumbers && phoneNumbers.length) {
phoneNumbers.map(eachPhoneNumberObj => {
transPayersNumbersArray.push(eachPhoneNumberObj.transPayersNumber);
})
}
});
console.log('TransPayersNumbersArray ==>', transPayersNumbersArray)
