In Pull[F, O, R], R is the return type. Pull represents a computation that emits some values on the Stream (of type O) and returns a new thing (R). In order to convert a Pull to a Stream, R must be Unit. This is because an FS2 Stream does not have the ability to terminate with a return value.
See here for the conversation
Stream[F, O] is monadic over O which are the output values emittedPull[F, O, R] is monadic over R which is used for stateful transformations

One of Apexlab's strategic partners, Olvasoegylet.io sent us a request for a book catalog application. They would like to have a public collection of books for their customers. You are the chosen one who may write POC (proof of concept) purely back-end (Node) JavaScript (Typescript) application which they could use to provide data for their various mobile application eg.: Book Renter.
