In this section, we will examine pattern matching in Clojure. Typically, functions that use conditional logic can be defined using the if, when, or cond forms. Pattern matching allows us to define such functions by declaring patterns of the literal values of their parameters. While this idea may appear quite rudimentary, it is a very useful and powerful one, as we shall see in the upcoming examples. Pattern matching is also a foundational programming construct in other functional programming languages.
In Clojure, there is no pattern matching support for functions and forms in the core language. However, it is a common notion among Lisp programmers that we can easily modify or extend the language using macros. Clojure ...
