Why should you learn an FP lang? Almost every programming language feature you love was invented in an FP lang decades before it became mainstream: - Garbage collection (lisp, 1950s) - Generics (ML, 1978) - Closures (scheme 1975) - Sum types and pattern matching (NPL 1970s)

Garbage collection became mainstream with Java in the 90s, 40 years after it was invented. Generics became mainstream as C++ templates in the 90s. Closures became mainstream in the 90s too with JavaScript

Part of the reason I'm fascinated by FP is that I wanna try out the cool and experimental features which could be the future of how we write code
