what's the difference between
for _, v in table do
and
for i, v in table do
other then counting how many times it looped over, is there any other difference like a difference in performance or other uses that for _, v in table haves?

this only serves to demonstrate that you are not using the variable "i"
i think there's no performance difference
tame jolt
oh
tame jolt
this only serves to demonstrate that you are not using the variable "i"
i guess that still is kind of useful to use
anyway thanks

there is potentialy a small perfomence dif, _ is marked for roblox as unused, roblox is probably not asignating the index to _

the first 2 things are vairables
i,v for example
_ is just no variable cuz you dont care about the index
so just cleaner code and be able to use i for something else

Cleaner how

Cleaner how
yes.

_ is parsed as a useless variable, using it in the for will tell roblox not to asigne the value, it remove like one instruction

It’s the same loop, like other people have said, “__” is basically just reminding yourself that you won’t be using that variable.
If you want to, you can absolutely still reference “__” but you should give it a proper name if you do.
not sure why the formatting is all fucked up now

i literally never use _ i always use i out of habit even if i dont need it

using _ is better for the understanding of the code, it also remove one instruction so roblox run faster (probably a nano second) using _ is kind of good to remind your self that you don't use it, like other said

The understanding partly

Ye it removes an instruction but it doesn’t do that much in terms of understanding

it do so mutch for readability
frank whale
Elaborate
errant osprey
when you see _ you know it will never be used, when you see i you need to check if its used
its why conventions are existing

That’s not readability

It’s a good indicator tho

Indicators are for readability ^^ like types for exemple
