pick()

The pick<T>() function is similar to the TypeScript Pick utility type, but it is used at runtime to return a new object with one or more properties picked from the provided object.

The generic T type is used to define the type of the object that is picked from.

Usage

import { pick } from '@spa-tools/utilities';

const person = {
  address: {
    city: 'New York',
    country: 'USA',
  },
  childrenAges: [8, 10],
  id: 1,
  name: 'John',
};

const newPerson = pick(person, 'address', 'name');
console.log(newPerson);
// -->
// {
//   address: {
//     city: 'New York',
//     country: 'USA'
//   },
//   name: 'John'
// }
