Functional Programming in a Pragmatic World
Functional Programming in a Pragmatic World Functional programming (FP) is a way to organize code that emphasizes small, predictable steps. It treats data as immutable and relies on pure functions that always yield the same result for the same input. In real projects, FP ideas help us write code that is easier to test and easier to reason about as software grows. Many teams use FP techniques without calling the style pure FP. You can start with a few gentle habits: prefer functions that do not modify their inputs, compose small functions into larger ones, and replace complex loops with map, filter, and, when appropriate, reduce. These changes often improve clarity without large rewrites. ...
