/**

|
* Creates a new object with the same keys as the given object, but with values generated
|
|
* by running each own enumerable property of the object through the iteratee function.
|
|
*
|
|
* @template T - The type of the object.
|
|
* @template K - The type of the keys in the object.
|
|
* @template V - The type of the new values generated by the iteratee function.
|
|
*
|
|
* @param {T} object - The object to iterate over.
|
|
* @param {(value: T[K], key: K, object: T) => V} getNewValue - The function invoked per own enumerable property.
|
|
* @returns {Record<K, V>} - Returns the new mapped object.
|
|
*
|
|
* @example
|
|
* // Example usage:
|
|
* const obj = { a: 1, b: 2 };
|
|
* const result = mapValues(obj, (value) => value * 2);
|
|
* console.log(result); // { a: 2, b: 4 }
