How does for i,v inpairs(Variable) do work?
Something = script.Parent for i, v in pairs(Variable) do Something.Position = Something.Position + Vector3.new(38, 20, 45) end
I, is the what? v, is what? How do the two relate to loops? How does the variable relate to the loop and something? How do these pieces of concept connect? Inpairs, does what, and how does this work? Can someone help explain this concept for me?

**i ** stands for **index **which is the table of things the function needs to iterate ( the repetition of a process) through.
**v ** is the value
So if you do:
game.Workspace:GetChildren()
The table is all the children in the workspace, and the value is the number of them
Here's a detailed answer that goes more in-depth. Hope you learned a thing or two! https://scriptinghelpers.org/questions/8605/what-does-for-_-in-pairs-mean
pairs from what i understand is a fancy shmancy function that returns a function, that is, an iterator function.
the standard way way of using an iterator function with for loops goes as follows:
for <tuple> in <function> do
the function is expected to return some things: - the iterator function (used on every item of the table) - the table that the iterator function operates on - the intitial value that controls if the loop is done
example of ipairs borrowed from the lua manual:
function iter (a, i)
i = i + 1
local v = a[i]
if v then
return i, v
end
end
function ipairs (a)
return iter, a, 0
end
however, iterator funcitions are foreign to me and thats as mush as i can tell you, so you can read more about it here:
