whats self and when to use it

[sage zealot]

i’ ve seen people literally spamming self all over the code, but I don’t quite understand what it does.

[simple fable]

it's for OOP

in methods of classes, self refers to the object that the method is called from

[tepid tapir]

;compile lua lua local t={ x=5 } function t.foo(self) print(self.x) end t:foo() -- notice how there's no arguments. the : implies 'self'.

oh so it is used for tables?

[tepid tapir]

To represent records, you use the field name as an index. Lua supports this representation by providing a.name as syntactic sugar for a["name"]. So, we could write the last lines of the previous example in a cleanlier manner as

a.x = 10                    -- same as a["x"] = 10
print(a.x)                  -- same as print(a["x"])
print(a.y)                  -- same as print(a["y"])

@tepid tapir do u suggest learning something else before learning these things or should i learn them now?

[tepid tapir]

there is no correct answer to this.

there's also no incorrect answer

[sage zealot]

i mean

do i need to understand a specific concept before learning these things? like something i need to understand them

[dry ore]

** You are now Level 5! **

[tepid tapir]

i suggest learning as much as you can as fast as you can. as they say, knowledge is power

[tepid tapir]

there's no correct order to learn things in. you either understand it or you don't. if you don't, you don't know enough to understand the concept yet, like understand the P=NP problem, you need to know some things about how code performance works before you can understand the problem, and that's not like some kind of gated knowledge, that's just the sheer nature of the problem, so you'll know quite fast if you need to learn more basics before learning the thing you're looking at.

i understand thanks👍😁
