+/**
+ * Creates a new Map with the same values but with keys transformed by the provided function.
+ *
+ * This function takes a Map and a function that generates a new key from each value-key pair.
+ * It returns a new Map where the keys are the result of applying the function to each entry,
+ * while the values remain the same.
+ *
+ * @template K - The type of keys in the Map.
+ * @template V - The type of values in the Map.
+ * @param {Map<K, V>} map - The Map to transform.
+ * @param {(value: V, key: K, object: Map<K, V>) => K} getNewKey - A function that generates a new key from a value-key pair.
+ * @returns {Map<K, V>} A new Map with transformed keys and the same values.
+ *
+ * @example
+ * const map = new Map([
+ *   ['a', 1],
+ *   ['b', 2],
+ *   ['c', 3]
+ * ]);
+ * const result = mapKeys(map, (value, key) => key.toUpperCase());
+ * // result will be:
+ * // Map(3) {
+ * //   'A' => 1,
+ * //   'B' => 2,
+ * //   'C' => 3
+ * // }
