What do you mean by “return stuff”? If you mean with a function, just check if v is what you want with an if statement and do return v as you would with any other return.

function isOne()
  local table = {}
  for i, v in pairs(table) do
      if v == 1 then
          return v
      end
  end
end

Just store them on a table.

local Storage = {}

for I, V in pairs(Table) do
    table.insert(Storage, I, V)
end

oh that’s a good idea i think i will do that

#5

so you cant use the return keyword for it though right?

Wouldn’t this just duplicate the existing table…? I’m not entirely sure what this accomplishes.

The return keyword will return the current value just like @ComplicatedParadigm said. If you want to, You can just declare a variable and check inside the loop if the value given is what you want to, Then make the previous declared variable the current value and break the loop.

local MyValue = nil

for I, V in pairs(Table) do
    if V == 1 then
        MyValue = V
        break
    end
end

I am aware that table.insert exists i just don’t come around to using it very often after seeing this i think ill use it more

for index, value in pairs(game.Workspace:GetChildren())
    return value
end

This just returns the first item in the table. If OP just wants the first item in a table then can just index it. It doesn’t make sense to use a for loop for this …

EX: To get the integer 3, in this table, we just use the [] operator.

local table = {3,4,5}
print(table[1])

i understand how to reference things in a table but thank you

FWIW: you can also manually iterate whatever table you have if you want to “return” a pair from a for loop. Return will terminate a loop within the iteration it’s called in and for loops aren’t callbacks so return isn’t actually going to give you anything back if you use it in a for loop alone, you need a closure.

local myChildren = something:GetChildren()

local index, child = next(myChildren)
while child ~= nil do
    myChildren[index] = nil
    -- Do something with index and child
    index, child = next(myChildren)
end

??? you can put local on for i,v is this Lua? did not know that
… I’ve got what i need i prefer if you guys keep from commenting on the post

#18 
local dict = {["a"] = true, ["b"] = false}

for i, v in pairs(dict) do
	print(i, v)
end

The variables “i” and “v” here are implicitly declared locally.
