A Better Understanding of Return?

[DasKairo (Cairo)]

I Already know that return Shockingly returns things, but I just want to get a better understanding of it.

Like For Example:

function Something()
  if Condition then
     return true -- What Exactly does this do?
  else
     return false -- And this
     end
end

For some reason, I can never get a good understanding of what return does, Like what is the point if it.
Can you Help?

Thanks

so in this context you could do:

local thing = Something()

if thing == true then
-- stuff
else
end

Yeah, i understand that part, but is there really anything else that i should know?

If you understand that then that is most of it, but maybe I misunderstand the question?

return allows you to give some value back to where ever you called it. For example, a simple add function:

function sum(x,y)
  return x+y
end

Can be used like this

value = sum(1,2)
-- value == 3

without return, the value would be lost once the function exits

the only other part of a return is that it ends the function

function test()
  print("This will run")
  return -- the function exits early because of this return
  print("This wont run")
end

return true and return false are the same way, just with booleans instead of integers

In addition to returning a single value, return can also return multiple values.

local function foo()
    local number1 = math.random(0, 10)

    return number1, number1 * 3, number1 ^ 2
end

local n1, n2, n3 = foo()

---

In some cases return can be used as an alternative to else.

local baz = "Roblox!"

local function bar()
    if baz == "Roblox!" then
        return
    end

    print(baz.." does not equal Roblox!")
end

Yeah, then I probably was overreacting that i had missed something because all of this makes sense to me, thanks tho
