High level composition of IO

io-high-compose.scala

import cats.effect._

val a = IO(...)
val b = IO(...)

a.map(transformA) // transform output of effect

a >> b // a then b, in other words, FlatMap

(a, b).parTupled // a and b concurrently, then use the output

IO.race(a,b) // race a and b, and cancel the slower one

IO.sleep(10.seconds) // non-blocking sleep
