Yeah obviously with constants for the set roles per value. Some languages call them enums, but the point is that what we pass and use is always still the smallest integer type possible. With the extra bonus that if the roles ever become composable, the same value type would likely suffice for a burglar and only thing needing refactoring would be bitshifting the constants.
But anyway, this turns out to be the weirdest hill I find myself willing to die on.
Yeah, but if it is about being an admin or not, hence the bool, it’d be idiomatic and reasonable to assume it to be false if we have no data. Unless we want to try and allow admin access based on no data. Having three states for a simple binary state is weird. And if it is not about just being an admin or not, the bool is inherently a too limited choice for representation.
Admin is a role though, was my point. And besides, if you check for three different states, and you decide to go with a boolean to represent that, I really find it hard to believe anyone would think it reasonable. It’s valid and it’s practical, but can you really say it’s reasonable?
I don’t do typescript, but wouldn’t a union of a null and a bool be just more resource intensive than simply using an unsigned byte-sized integer? I struggle to find reasons to ever go for that over something more reasonable and appropriate for what it attempts to represent (3 distinct states as it stands, and likely in future more than just 3 when they have a need for more granularity, as you’d often do with anything you’d need an admin role distinction in the first place), but likely I’m just not familiar with ts conventions. Happy to hear the reasoning for this though.
Yeah let’s use a union of a boolean and null to represent role, something that inherently represents more than two (…or three, I guess) different values, as opposed to something like an integer.
Even if the name is clearly misleading in this specific case, the entire choice of using a bool here is just bad because it’s almost guaranteed you’re going to expand on that in future and then you’ll just have to entirely rewrite the logic because it simply can’t accommodate more than two values (or three with the null union… 🙈), while it gives absolute zero benefits over using something more reasonable like an integer to represent the roles, or in this case, admin, not-admin and guest. Even if you’ll end up with just admin, non-admin and guest, the integer would still work great with no disadvantages in terms of amount of code or whatever. Just increased legibility and semantical accuracy.
Not to mention that there’s zero reason to combine the state of being logged in and the role in which you’re logged in in one variable… those are two different things. They will remain two different things in future too…
I mean they’re already chaining elseifs (basically matching/switching, while doing it in an inefficient way to boot 🥴) as though there were an n amount of possible states. Why not just make it make sense from the start instead of whatever the hell this is?
I don’t really follow you there, wouldn’t it be exactly the opposite and wouldn’t checking for nulls be, as a premise, more wasteful? But doesn’t really matter, time to digress. I’m conventionally educated as an engineer so what I know and find reasonable today might be outdated and too strict for most contemporary stuff.
