Quick question (for i,v in pairs and for _,v in pairs)

[vovcher (youareabulgarian)]

whats the difference between:

for _,v in pairs

and

for i,v in pairs

Just a different variable name, they are the same

_ is a blank global, you cannot use it

None, in the former example the index isn’t needed so the dummy variable _ is used. In the latter, it is being used so a more meaningful identifier is used.

May someone explain to me what for _, in pairs means?

The use of an underscore as an identifier doesn’t really mean anything special in Lua, or in most languages for that matter. Programmers use it to represent nothing. Say, for instance, you had a function that returns 2 values, but in your situation the first one doesn’t matter. You can’t just skip it, you still need to account for it because the order of how data is returned is based on position. For instance: local function get_name() return "John", "Doe" end local _, last_name = get_name…

Basically there is no differences, “_” is normally used when the variable is not going to be used.

[sjr04 (uep)]

It can be used. The _ has no special meaning syntax-wise. It is still a valid identifier. Although the point of that is to not

When I attempt to print it in code, it will error

[sjr04 (uep)]

Then that was an issue with your code, because this is fine

[RakNetProtocol]

Oh wait, my bad, it actually screams at me that this is a placeholder

[sjr04 (uep)]

Yes that is the Luau linter

[RakNetProtocol]

I know, I just forgot if it errored or warned

You didn’t just assign a value to an empty global… GUARDS! Get him!
