Loops

Try to avoid loops when it is simple to do so because loops require change of tate to terminate and change of state is an opportunity for bugs.

while(true) do
    printfn "Hello World"

for i = 1 to 10 do
    printfn "%A" i

let arr = ["One";"Two";"Three"]
for t in arr do
    printfn "%A" t
