In this article I try to explain why Haskell keeps being such an important language by presenting some of its most important and distinguishing features and detailing them with working code examples. The presentation aims to be self-contained and does not require any previous knowledge of the language.

TypeScript does not have any pattern matching functionality built in. This article shows several ways how you can replicate the core of a simple pattern matcher using a few simple structures and functions within TypeScript. Resulting code will have improved maintainability and better runtime type safety when done right.
