What the heck is data-oriented programming?

Software Engineering Unlocked

This episode is sponsored by Tonic.ai - where your data is modeled from your production data to help you tell an identical story in your testing environments.

Yehonathan is a software developer, author, and speaker. He has tons of experience in full-stack development using various languages such as Java, Javascript, and Ruby. But his favorite language is Clojure. He bundled all this experience and knowledge into his book Data-Oriented Programming, which is already available for beta-readers on Manning Publications and should be finished this summer.
