removeKey

Method is IN-PLACE. Also, compatible to call with Array

Definition

function removeKey(...keys: string[]) : this;

Example

Another simple one... You can provide a list of keys or only single key to remove in the object

import '@marthvon/protopp';
// or
import '@marthvon/protopp/objectpp/methods/removeKey.js';

const o = { a: 1, b: 2, c: 3, d: 4 };

console.log(o.removeKey('a'));
// Outputs { b: 2, c: 3, d: 4 } 

console.log(o.removeKey('b', 'c'));
// Outputs { d: 4 } 

console.log(o);
// Outputs { d: 4 } 
// Notice that the changes are inplace,
// hence it doesn't create a new array when you remove a key

if you need it to make another copy... I would suggest using it inconjunction with the .deepCopy method, Or performing a shallow copy

o.deepCopy().removeKey(...);
// Or, if you want to preserve the references then do a shallow copy
{ ...o }.removeKey(...);
