How to delete an object property?

Question

JavaScript

Not deleted :(

Answer 1

Well, it's probably not configurable .
Recreate the object:

const {password, ...rest} = user;
console.log(password);
console.log(rest);
return rest;

Answer 2

delete deletes only its own properties and does not delete inherited ones, to delete an inherited property of an object, you need to delete it in the prototype of the object in which it is defined.
delete cannot remove non-custom properties.
