Remove elements from object in Javascript/Angular

Question

I have an object

let myObj = {"info1": "", "info2": "", "info3": "", ......}

Here I want to remove info1 and info2. I tried splice, but it is throwing error. The pop method is also not working. How can I achieve that?

Please show what you have tried and what errors you are getting. — Heretic Monkey, May 17 '21 at 13:42
The example you have provided is an object. Use delete operator to remove the desired properties. — zx01, May 17 '21 at 13:43
@RajkumarKalaimani the thing you call an array in you question is an object `{"a":"a", "b":"b", "c":"c"}`, not an array `[a,b,c]`. — Andrew Allen, May 17 '21 at 13:49
Thats an ```object``` so to delete any properties from object use ```delete property.myObject```. That might help :-) — , May 17 '21 at 13:49

You can achieve this various ways:

Delete

const data = { "info1": "", "info2": "", "info3": "" };

delete data.info1;
delete data.info2;

console.log(data);

Filter

const data = { "info1": "", "info2": "", "info3": "" };
const ignore = ['info1', 'info2'];

const copy = Object.fromEntries(Object.entries(data)
  .filter(([k, v]) => !ignore.includes(k)));

console.log(copy);

Destructure

const data = { "info1": "", "info2": "", "info3": "" };

const { info1, info2, ...copy } = data;

console.log(copy);
