when I write a function. How to understand - when to create a class for it, and when to write it in a Helper type class (i.e. a class for auxiliary functions)?

when I write a function. How to understand - when to create a class for it, and when to write it in a Helper class (ie a class for auxiliary functions)?

Answer 1

A helper class or file is usually a bad idea. It attracts garbage and bicycles.
There is nothing wrong with individual functions. But if you get used to OOP, then most functions naturally become class methods.

Answer 2

If a function can be generalized to several unrelated classes used in a program, then it is "helper".
