Difference between coroutine.wrap ( function f ) and calling a normal function?

Hi, I saw on wiki regarding coroutine.wrap and I’m just wondering in what case would I use this?

I understand how a function can be wrapped in it then called later, but what’s the difference from just calling a function normally e.g. lua"repeatThis()" and putting in a lua local f = coroutine.wrap(repeatThis) then calling lua"f()"

Just trying to get used to understanding coroutines and knowing where I can use them, I humbly ask if anyone could also elaborate on the other coroutine methods in the wiki in a scenario that would be necessary to use them coroutine | Roblox Creator Documentation

Thanks!

Code inside coroutine.wrap runs in a different thread. One use case is running loops without delaying the script or having to make multiple scripts.

example:

for i = 1, 25 do 
	coroutine.wrap(function()
		while task.wait(.2) do 
			print("hi i'm loop "..i)
		end
		print("doesn't run")
	end)()
	print("runs cause it's outside the loop thread")
end

This post provides a great explanation related to coroutines.
