In this example, we match the value of i with different patterns: Web this selection operation is called pattern matching; Here are many examples of how to use patterns with data: Web learn how to use pattern matching to access lists in ocaml, a functional programming language. To summarize, it is better to use when when it is impossible or nearly impossible to express. Web pattern matching with functions.

Web this selection operation is called pattern matching; Web in ocaml, pattern matching provides a means to inspect data of any kind, except functions. Pattern matching allows to match something with different cases: The type of a linked list of integers is int list, and in general the type of a linked list of foo. Web ocaml does pattern matching slightly differently than other functional languages, but individual differences aside, pattern matching is awesome. Web well, it's useful when we start doing pattern matching on lists, which i'll talk about below. If i matches 1, it returns 1st,. To summarize, it is better to use when when it is impossible or nearly impossible to express. Tnormal | tfire | twater. Web this chapter will focus on two common elements of programming in ocaml:
