/**
 * Takes a function and a functor, applies the function to each of the functor's values, and returns a functor of the same shape.
 * It works for both Arrays and Objects.
 *
 * @example
 * ```typescript
 * const double = x => x * 2;
 *
 * map(double, [1, 2, 3]); //=> [2, 4, 6]
 *
 * map(double, {x: 1, y: 2, z: 3}); //=> {x: 2, y: 4, z: 6}
 * ```
 *
 * @param fn Map function to apply
 * @param iterable collection to iterate
