import {includeKeys, excludeKeys} from 'filter-obj';
const object = {

//=> {foo: true}
const newObject2 = includeKeys(object, ['bar']);

Type: object
The source object to filter properties from.
Type: (sourceKey: string | symbol, sourceValue: unknown, source: object) => boolean

Type: Array<string | symbol> | Set<string | symbol>

lodash.pick is a method from the Lodash library that creates an object composed of the picked object properties. It is similar to filter-obj but is part of a larger utility library, which might be preferable for users who need other utility functions.
object-filter is another npm package that provides similar functionality to filter-obj, allowing filtering of object properties based on a predicate function. It compares to filter-obj in terms of functionality but might have different implementation details or additional options.
