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.
I propose that we can extend Mirrors to operations, and use the most natural DSL of all - plain trait definitions.
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 beginner-friendly talk we'll try to find out using the power of Scala and functional programming techniques.
Listen to a story of how we have dealt with 201 obstacles allowing us to run multithreaded programs natively!
