Just create a global object and stuff your variable in there. Now you have a global singleton and that's not a purely bad practice :D

Just call it "state management" and nobody will even care.

Not necessarily a bad practice if the singleton is immutable, and it’s provided via dependency injection for example.

As a hobby coder: "mmmhm, mmmm, mmhm... I know some of these words!"

Software dev is full of obscure keywords that describe otherwise pretty simple or basic concepts you stumble upon in practice naturally and that you probably already understand.

  • singleton: a class/object that is designed to be single use, i.e. only ever instantiated with a single instance. Typically used when you use class/objects more for flow control or to represent the state of the program itself, rather than using it to represent data
  • immutable: read-only, i.e. unchangeable
  • dependency injection: basically when you pass a function or object into another function object, thereby extending their effective functionality, typically for modular code and to separate concerns.

Here's one more of my favourite examples of such a keyword: memoization

Ahh yes memoization, the complicated way to say "remember this, I might need it again"

Important to contain all your mess to one side of the room, makes it easier to manage

Yeah yeah let's put all the eggs in one basket

So you saying, just the tip?

Real enterprise programmers know that everything should be on the stack... so they declare a List《void*》 in main.

[–] idunnololz 8 points 11 months ago

But we might need to add more features in the future so it might not just be a list in a few years. Better encapsulate it in a few layers of abstractions just to be safe.

Ah yes. Global Objects, AKA the thinnest of condoms, lol.
