Data in Clojure

Abstract

Clojure is a dynamically typed language, which means that you never need to explicitly define the data type of symbols, functions, or arguments in your programs. However, all values still have a type. Strings are strings, numbers are numbers, lists are lists, etc. If you try to perform an unsupported operation on a type, it will cause an error at runtime. It is the programmer’s responsibility to write code in such a way that this does not happen. This should be very natural to those with a dynamic language background, while it will no doubt take some getting used to for those who have only used static languages in the past.
