In this episode I talk with Yehonathan Sharvit. We talk his upcoming book Data Oriented Programming, what Data Oriented Programming is, how it differs from Functional Programming, how DOP fits with typed languages, and more.Our Guest, Yehonathan Sharvit@viebel on Twitterviebel on Githubhttps://blog.klipse.tech/Data Oriented Programming from ManningAnnouncementsThe Big Elixir is taking place March 24th and 25th in New Orleans.
