this is the sample json format in my application.
my arr = [
{
"id": 12,
"creationTimestamp": "2021-09-15 15:01:11",
"groupName": "one",
"$$hashKey": "object:15"
},
{
"id": 13,
"creationTimestamp": "2021-09-15 15:01:14",
"groupName": "two",
"$$hashKey": "object:16"
},
{
"id": 14,
"creationTimestamp": "2021-09-15 15:01:19",
"groupName": "three",
"$$hashKey": "object:17"
}
]
according to my requirement i need to change id --> groupId. After i need to assign it for the new array
my array2 [
{
"groupId": 12,
"creationTimestamp": "2021-09-15 15:01:11",
"groupName": "one",
"$$hashKey": "object:15"
},
{
"groupId": 13,
"creationTimestamp": "2021-09-15 15:01:14",
"groupName": "two",
"$$hashKey": "object:16"
},
{
"groupId": 14,
"creationTimestamp": "2021-09-15 15:01:19",
"groupName": "three",
"$$hashKey": "object:17"
}
]
how i do this modification using java script
You can easily achieve the result using map
const my_arr = [
{
id: 12,
creationTimestamp: "2021-09-15 15:01:11",
groupName: "one",
$$hashKey: "object:15",
},
{
id: 13,
creationTimestamp: "2021-09-15 15:01:14",
groupName: "two",
$$hashKey: "object:16",
},
{
id: 14,
creationTimestamp: "2021-09-15 15:01:19",
groupName: "three",
$$hashKey: "object:17",
},
];
const result = my_arr.map(({ id, ...rest }) => ({ groupId: id, ...rest }));
console.log(result);/* This is not a part of answer. It is just to give the output fill height. So IGNORE IT */
.as-console-wrapper { max-height: 100% !important; top: 0; }To do this you can use the Object and Array methods in js .. See Below
let myArray = [
{
"id": 12,
"creationTimestamp": "2021-09-15 15:01:11",
"groupName": "one",
"$$hashKey": "object:15"
},
{
"id": 13,
"creationTimestamp": "2021-09-15 15:01:14",
"groupName": "two",
"$$hashKey": "object:16"
},
{
"id": 14,
"creationTimestamp": "2021-09-15 15:01:19",
"groupName": "three",
"$$hashKey": "object:17"
}
]
let newArray = [];
myArray.forEach(obj =>{
Object.assign(obj , { groupId : obj.id} );
delete obj.id;
newArray.push(obj);
});
console.log(newArray);
