Tl;dr: don’t use @property during design, it’s almost certainly the wrong pattern. But use it to retrofit a method to a value.
this is a method, and always was a method, I just wanted it to look like an attribute for aesthetic reasons
I think “aesthetic reasons” is an oversimplification. There are certain assumptions a developer makes when reading some code that uses properties. While these assumptions are not clearly defined and may differ per developer, I think there is a common core.
(1) There are no side-effects. The object is not mutated (or any other object), no IO takes place.
(2) The time and space complexity is O(1).
(3) The result is consistent. Consequent calls to the property should return the same value unless there is a mutation between them.
The combination of properties 1 and 3 makes it a pure function, which is also useful in compiled or jittable languages because it allows for a variety of optimizations.
(tried to delete this comment but somehow didn’t work, I re-read the article and have a different outlook, sorry for the low effort comment)
Nah, I think I’ll continue to.
