Does calling a function in a function run synchronous?

[TTTDeathwish1 (MTAyman)]

Sorry for the confusing title. I just wanted to know if when a script executes like so

local function doSomething()
--some long code that does stuff
return somevariable
end

remote:Connect(function()
    local var = doSomething()
-- do some more stuff <-- Would this code execute before the variable can be returned?
end)

Calling a function is inherently synchronous.

[domineersXII (xDom)]

function test()
	local number = add(1,1)
	
	print(number)
end

function add(a,b)
	print("add function")
	task.wait(5)
	return a+b
end

test()

In a situation like this the “test” function would wait until the value is returned before printing number.
