Best Practice: Add Initial Value to reduce() to Improve Robustness #212
Description
Descriptions:
The function that finds the nearest direction using reduce() does not include an initial value. While the array is currently predefined, adding an initial value would improve code robustness and prevent potential future issues.
Why Consider This Change?
- If DIRECTIONS is modified dynamically in the future, reduce() may throw a TypeError when the array is empty.
- Including an initial value makes the function more readable and predictable, especially for future contributors.
- It ensures the function behaves consistently, even with a single-element array.

Benefits of This Change:
- Prevents potential runtime errors if the array is ever empty
- Future-proofs the function against modifications
- Enhances readability for maintainers and contributors
