I have a JSON structure and I need to remove the entire StartGeotag object from the array.
[{
CreatedDate: "2022-02-17T10:30:07.0442288Z"
DeletedDate: null ProjectId: "05b76d03-8c4b-47f4-7c20-08d9e2990812"
StartGeotag: {
Type: 'Point',
Latitude: '33.6607231',
CreatedDate: '2022-02- :34:46.5389961Z'
}
StartTime: "2022-02-17T10:30:05.828Z"
}]
Utilizing the ES6 Spread Operator allows you to accomplish this task:
To remove specific keys, simply provide those keys as arguments, and ...rest will return the remaining arguments.
var data = [{ CreatedDate: "2022-02-17T10:30:07.0442288Z",
DeletedDate: null,
ProjectId: "05b76d03-8c4b-47f4-7c20-08d9e2990812",
StartGeotag: {Type: 'Point', Latitude: '33.6607231',
CreatedDate: '2022-02- :34:46.5389961Z'},
StartTime: "2022-02-17T10:30:05.828Z"}]
const res= data.map(({StartGeotag, ...rest}) => ({...rest}));
console.log(res);To utilize object destructuring assignment introduced in ES6, you can destructure objects easily.
See the code snippet below for a demonstration :
let jsonObj = [{
CreatedDate: "2022-02-17T10:30:07.0442288Z",
DeletedDate: null,
ProjectId: "05b76d03-8c4b-47f4-7c20-08d9e2990812",
StartGeotag: {
Type: 'Point',
Latitude: '33.6607231',
CreatedDate: '2022-02- :34:46.5389961Z'
},
StartTime: "2022-02-17T10:30:05.828Z"
}];
let res = jsonObj.map(({StartGeotag, ...remainingItems}) => remainingItems)
console.log(res);To easily extract specific data from your object, you can use object destructuring.
[{ CreatedDate: "2022-02-17T10:30:07.0442288Z" , DeletedDate: null, ProjectId: "05b76d03-8c4b-47f4-7c20-08d9e2990812",
StartGeotag: {Type: 'Point', Latitude: '33.6607231', CreatedDate: '2022-02- :34:46.5389961Z'},
StartTime: "2022-02-17T10:30:05.828Z"}].map(({StartGeotag, ...item}) => item)
If you specifically need only the StartGeoTag object, you can achieve that like so:
[{ CreatedDate: "2022-02-17T10:30:07.0442288Z" , DeletedDate: null, ProjectId: "05b76d03-8c4b-47f4-7c20-08d9e2990812",
StartGeotag: {Type: 'Point', Latitude: '33.6607231', CreatedDate: '2022-02- :34:46.5389961Z'},
StartTime: "2022-02-17T10:30:05.828Z"}].map(({StartGeotag}) => StartGeotag)
