 * Creates an object with the same values as the original, but with new keys generated

 * @param {Object} object - The object to map.
 * @param {Function} [iteratee = identity] - The mapping function.
 * @returns {Object} - The new object with mapped keys.
 *
 * @example
 *
 * const users = {
 *   john: { age: 23 },
 *   jane: { age: 31 },
 *   jack: { age: 27 }
 * };

 * console.log(uppercaseKeys);
