mapValues

import { mapValues } from '@tulx/utils';

/**
 * Creates an object with the same keys as object and values generated by running each own enumerable string keyed property of object thru iteratee.
 *
 * @param object - The object to iterate over.
 * @param iteratee - The function invoked per iteration.
 * @returns Returns the new mapped object.
 *
 * @example
 * ```ts
 * const users = {
 *   'fred': { 'user': 'fred', 'age': 40 },
 *   'pebbles': { 'user': 'pebbles', 'age': 1 }
 * };
 * mapValues(users, (o) => o.age); // { 'fred': 40, 'pebbles': 1 }
 * ```
