A lot of languages have very flexible type systems, such as F# with its inferred (and extremely well inferred at that) type system, or JavaScript with it’s untyped nature. Clojure hits a happy middle ground (for me, at least) – It’s dynamically typed (or “gradually typed”, if that’s your cup of tea).</p> <p>Why is the typing important? Polymorphism. Most of you probably learned polymorphism from your introduction to object-oriented programming course/book which was probably in C++ or Java. While it’s true, polymorphism is blatantly obvious in OOP, it’s still a thing in functional languages, too. Clojure, considering it runs on the JVM as well, is certainly no exception. Today we’re going to talk about Multimethods, a particular form of runtime polymorphism. And since I’m in a playful mood, our example is going to involve Power Rangers.</p>
