Roll your own Computation blocks in Kotlin

Roll your own Computation blocks in Kotlin

almost 5 years ago

Computation blocks empower library authors and users to build ad-hoc operators and DSLs over any data-type getting rid of API complexity and simplifying composition. In this talk, we will learn how we can build Computation blocks over Kotlin suspend functions & the Arrow Continuations library's reset / shift capabilities. We will demonstrate the composition of well known JVM data-types and patterns such as lists, futures, streams, and IOs, where callback chains can be simply replaced by a single
