Compatibility with Lodash
The pick
function from es-toolkit/compat
allows you to select deep properties from an object.
typescript
import { pick } from 'es-toolkit/compat';
const obj = { a: { b: { c: 1 } }, d: { e: 2 }, f: { g: 3 }, 'f.g': 4 };
const result = pick(obj, ['a.b.c', 'f.g']);
// result will be { a: { b: { c: 1 } }, 'f.g': 4 }
