This means programs are easier to understand. I.e, A function should only return a value to the invoker and should not affect any external state. No side effects: A function or operation should not change any state outside of its functional scope.In functional programming state is not eliminated, instead, its made visible and explicit No implicit state: Hidden/Implicit state should be avoided.No Data mutations: It means a data object should not be changed after it is created.Hence in functional programming, there are two very important rules

Please keep in mind, though this post is about TypeScript, you can easily do the same in JavaScript as well since TypeScript is just a typed superset of JavaScript.įunctional programming is a programming paradigm-a style of building the structure and elements of computer programs-that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. I’m also not gonna discuss the pros and cons of functional programming in general.

I’m not gonna dive into all functional programming concepts in detail, instead, I’m gonna focus on things that you can do in TypeScript which are in line with functional programming concepts. If you are looking for functional programming in Java or Golang check other posts in the series. If you are a TypeScript/JavaScript developer and wants to venture into functional programming, do not worry, you don’t have to learn functional programming oriented languages like Haskell or Clojure since JavaScript and hence TypeScript has you covered and this post is for you. Like other programming paradigms/styles, functional programming also has its pros and cons and one may prefer one paradigm over the other. There is a lot of hype around functional programming(FP) and a lot of cool kids are doing it but it is not a silver bullet.
