Working with pattern matching
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 ...
