How can I skip the wait time of a function in a for loop?

I heard of something called coroutine and I checked the documentation but I am still confused. How could I skip the wait time for a function (because it takes like 20 seconds and I want it to happen simultaneously) in a for in pairs loop?

Here is the loop:

for index,stem in pairs(stems) do
	grow(stem)
	wait(math.random(10,20)/100)
end
for index,stem in pairs(stems) do
	task.spawn(function
		grow(stem)
		wait(math.random(10,20)/100)
	end)
end

for index,stem in pairs(stems) do
	coroutine.wrap(function
		grow(stem)
		wait(math.random(10,20)/100)
	end)()
end

You can use coroutines/task.spawn() to achieve this. Both create a new thread to handle the execution of code while the main thread continues with the execution of the script.

im getting this error:

for index,stem in pairs(stems) do
	task.spawn(function()
		grow(stem)
		wait(math.random(10,20)/100)
	end)
end

for index,stem in pairs(stems) do
	coroutine.wrap(function()
		grow(stem)
		wait(math.random(10,20)/100)
	end)()
end

I apologise, I forgot to add () to each function body inside both task.spawn() and coroutine.wrap() calls.

it works! Thank you!

its okay!
