/**

|
* Creates a new Set with elements transformed by the provided function.
|
||
|
|
*
|
||
|
|
* This function takes a Set and a function that generates a new value from each element.
|
||
|
|
* It returns a new Set where the elements are the result of applying the function to each element.
|
||
|
|
*
|
||
|
|
* @template T - The type of elements in the input Set.
|
||
|
|
* @template U - The type of elements in the output Set.
|
||
|
|
* @param {Set<T>} set - The Set to transform.
|
||
|
|
* @param {(value: T, value2: T, set: Set<T>) => U} getNewValue - A function that generates a new value from an element.
|
||
|
|
* @returns {Set<U>} A new Set with transformed elements.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* const set = new Set([1, 2, 3]);
|
||
|
|
* const result = map(set, (value) => value * 2);
|
||
|
|
* // result will be:
|
||
|
|
* // Set(3) { 2, 4, 6 }
