This talk aims to equip the audience with the minimum required bagage to get comfortable working with contravariance.
Contravariance can throw many developers off the first time they run into it. This talk aims to equip the audience with the minimum required bagage to get comfortable working with contravariance. We'll begin by building up intuition for what it means for a type parameter to be in contraviariant position, before moving on to concrete examples.
In this talk, we will demonstrate some elegant applications of functional programming in Scala, with even more elegant visual results - all with live code and real-time output.
In this talk, we will take a tour around the `error` function. Starting from the simple use-cases and ending up with sophisticated yet developer-friendly error messages.
Join me for a fun and possibly opinionated talk about the state of Scala and other JVM languages.
