What Do Patterns Match? A constructor pattern C(p1, ..., pn) matches all the values of type C (or a subtype) that have been constructed with arguments matching the patterns p1, ..., pn. A variable pattern x matches any value, and binds the name of the variable to this value A co...

So far, we’ve explored some of the basic functional cornerstones of Scala: immutable data types and the passing of functions as parameters. The third cornerstone of functional programming is pattern matching. Pattern matching provides a powerful tool for declaring business logic in a concise and ...

Pattern matching in TypeScript has become an increasingly important feature for building robust and type-safe applications. While TypeScript doesn’t have built-in pattern matching like some functional programming languages, we can achieve similar functionality using various TypeScript features and techniqu...
Pattern matching in functional programming languages is a way to break up expressions into individual cases. We are going to go through how to pattern match in PureScript with simple patterns, guards, array patterns and record patterns. greater :: Int -> Int ->Int ...
Structural pattern matching is a powerful control flow construct invented decades ago that’s traditionally used by compiled languages, especially within the functional programming paradigm. Most mainstream programming languages have since adopted some form of pattern matching, which offers concise and ...
