About this Episode

Joël and Sally examine the simpler components of programming and why using basic data structures may not always be the best approach to solving a problem.

Our hosts cover all the telltale signs and symptoms of primitive obsession, what it is, it’s drawbacks and limitations, and how to avoid it creeping into your own work.
