Tab vs spaces, vim vs emacs, types vs tests, our community is full of these conflicts. In this talk, you will explore the latter: what is the impact of types in our programs? Can types help write more efficient tests? If so, how?
You will discover some basic type theory and concrete examples, in order to see how types can constrain the design space. More importantly, you will learn how to select the right type for the job.
