+* Creates a new object with the same values as the given object, but with keys generated
+* by running each own enumerable property of the object through the iteratee function.
+*
+* @template T - The type of the object.
+* @template K1 - The type of the keys in the object.
+* @template K2 - The type of the new keys generated by the iteratee function.
+*
+* @param object - The object to iterate over.
+* @param [getNewKey] - The function invoked per own enumerable property, or a path to generate new keys.
+* @returns Returns the new mapped object.
+*
+* @example
+* // Example usage:
+* const obj = { a: 1, b: 2 };
+* const result = mapKeys(obj, (value, key) => key + value);
+* console.log(result); // { a1: 1, b2: 2 }
