I have Java script array like this:
arr = [
{
"email": "info@gmail.com",
"phoneNumber": "++255 638-1527",
},
{
"email": "@gmail.com",
"phoneNumber": "+255 532-1587",
},
{
"email": "@gmail.com",
"phoneNumber": "+255 613-1587",
"info": [
{
"date": "2022-02-19",
"count": 1
},
{
"date": "2022-03-17",
"count": 9
},
{
"date": "2021-02-10",
"count": 10
}]
}
]
I need to convert above array of objects arr into object with key-value pair like below
arr =
{
"+255 638-1527":{
"email": "info@gmail.com",
"phoneNumber": "+255 638-1527",
},
"+255 532-1587":{
"email": "@gmail.com",
"phoneNumber": "+255 532-1587",
},
"+255 613-1587":{
"email": "@gmail.com",
"phoneNumber": "+255 613-1587",
"info": [
{
"date": "2022-02-19",
"count": 1
},
{
"date": "2022-03-17",
"count": 9
},
{
"date": "2021-02-10",
"count": 10
}]
}
I need the it like this JSON, in the form of key-value pair. How can I achieve this?
I need the data like this in order to render the output, can someone please help me with this?
Use Object.fromEntries like this:
const arr = [{"email": "info@gmail.com","phoneNumber": "++255 638-1527",},{"email": "@gmail.com","phoneNumber": "+255 532-1587",},{"email": "@gmail.com","phoneNumber": "+255 613-1587","info": [{"date": "2022-02-19","count": 1},{"date": "2022-03-17","count": 9},{"date": "2021-02-10","count": 10}]}];
const result = Object.fromEntries(arr.map(item =>
[item.phoneNumber, item]
));
console.log(result);
