Creating your own generic map functionality

Develop your own implementation of the map function using generics. The function should accept two arguments: an array of elements of any type and a callback function that transforms each element. The result should return a new collection containing the values obtained after applying the callback to all elements of the original array.

function myMap<T, U>(source: T[], transform: (item: T) => U): U[] {
    // implementation
}

Requirements:

• The function must be fully type-safe.
• Do not modify the original array.
• Ensure correct operation with empty arrays and various data types.
• Do not use the built-in Array.prototype.map.
