What are the best practices for defining constants in programming?

Is it better to define constants in a separate file?

It can be beneficial to define constants in a separate file for better organization and maintainability, especially in larger projects.

What about using enums instead of constants?

Enums can be a great alternative to constants, especially when you have a fixed set of related values, as they provide better type safety.
