/**
|
|
* 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 K - The type of the new keys generated by the iteratee function.
|
|
*
|
|
* @param {T} object - The object to iterate over.
|
|
* @param {(value: T[keyof T], key: keyof T, object: T) => K} getNewKey - The function invoked per own enumerable property.
|
|
* @returns {Record<K, T[keyof T]>} - 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 }
