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

You can use Object.assign(), delete

var not = ["a", "b"]; // properties to delete from obj object
var o = Object.assign({}, obj);
for (let n of not) delete o[n];

Alternatively

var props = ["c", "d"];
let o = Object.assign({}, ...props.map(prop => ({[prop]:obj[prop]})));
