2 * Creates a new Map with the same keys but with values transformed by the provided function.
3 *
4 * This function takes a Map and a function that generates a new value from each value-key pair.
5 * It returns a new Map where the values are the result of applying the function to each entry,
6 * while the keys remain the same.
7 *
8 * @template K - The type of keys in the Map.
9 * @template V - The type of values in the Map.
10 * @param {Map<K, V>} map - The Map to transform.
11 * @param {(value: V, key: K, object: Map<K, V>) => V} getNewValue - A function that generates a new value from a value-key pair.
12 * @returns {Map<K, V>} A new Map with the same keys and transformed values.
13 *
14 * @example
15 * const map = new Map([
16 * ['a', 1],
17 * ['b', 2],
18 * ['c', 3]
19 * ]);
20 * const result = mapValues(map, (value) => value * 2);
21 * // result will be:
22 * // Map(3) {
23 * // 'a' => 2,
24 * // 'b' => 4,
25 * // 'c' => 6
26 * // }
