1 script and 2 while loops running at once?
while wait(1)do print'1' end while wait(2)do print'2' end
It never prints 2. Is it possible to make the both while loops start running at once without putting them into two different scripts?

From what I know, you can't run two separate loops at the same time unless one was inside a function that was fired by an event while the same script was looping something else. Troidit 253 — 7y

Spawn
First of all: don't use coroutine if you're only using it to make "threads" that make code "happen at the same time".
A good test: if you're not meaningfully using coroutine.yield, don't use coroutine at all.
Instead, use spawn and delay to create "background threads"
spawn(function()
-- "in the background" loop
while true do
print("background loop")
wait()
end
end)
while true do
print("foreground loop")
wait()
end
Avoid threads
Second of all: it is usually a mistake to use spawn / have multiple threads. Your code can really quickly become confusing and complicated.
By interleaving work, you can do multiple things at the same time, in a very controlled way.
e.g., why wouldn't you just use this instead?
while true do
print("background loop")
print("foreground loop")
wait()
end
