Which is considered as a better style? Enums, sealed classes with singletons, or class with companion objects with val?

[Nir]

For what?

[Nir]

Enums are pretty limited so I would think if you can use enums for something there's a decent chance it's the right choice

[Animesh Sahu]

Enums are limited? I don't think so, they behave the same as the other two options.

[Nir]

?

[Nir]

They are more limited because there is less they can express

[Nir]

Rule of least power

[Animesh Sahu]

You can have variables and functions in enums, I think you're confused with enums in low level langs 😅

[Nir]

Dude no...

[Nir]

Enum class instance can only be one of several globals of the exact same type

[Nir]

That's all it can do

[Nir]

Sealed classes do much more than that

[Animesh Sahu]

Yes, but sealed classes with singletons (objects) are the same....

[Nir]

Yes, that's the point

[Nir]

Sealed classes can reasonably emulate enum classes

[Nir]

Enum classes cannot reasonably emulate sealed classes

[Nir]

Do you understand?

[Nir]

It's very common in programming languages that feature A can emulate B but B cannot emulate A. E.g. macros vs functions in lisp

[Animesh Sahu]

The question wasn't about this, I wanted to store group of constant values. And thats the quesiton: Enums, sealed classes with singletons, or class with companion objects with val?

[Nir]

yes, and I answered your question

[Nir]

All other things being equal pick the least powerful language feature that serves the purpose

[Nir]

This is assuming there is some notion of mutual exclusivity in your constants

[Nir]

Otherwise I would say none of the above, just have a bunch of top level globals in the same file
