Explore functional programming in this 42-minute conference talk from GOTO Berlin 2018. Discover how functional programming has moved beyond academia into real-world applications, with languages like Clojure, Scala, Elixir, and F#. Learn about key concepts such as immutability and higher-order functions, and how functional techniques are being incorporated into traditional languages like Java and Ruby. Gain insights from Russ Olsen, author and VP at Cognitect, as he demystifies functional programming and its practical applications in modern software development. Enhance your understanding of this increasingly important programming paradigm and its potential to improve code quality and maintainability.
