How to omit specific properties from an object in JavaScript

Question

Is there a clean way to return a new object that omits certain properties that the original object contains without having to use something like lodash?

Answer 1

There's the blacklist package on npm which has a very flexible api.

Also a situational trick using the object rest-spread proposal (stage-3).

const {a, b, ...rest} = {a: 1, b: 2, c: 3, d: 4};
a // 1
b // 2
rest // {c: 3, d: 4}

This is often used in react components where you want to use a few properties and pass the rest as props to a

or similar.
