Functional Programming in TypeScript 5.5: A Practical Guide

Opening Hook

You've just deployed your TypeScript application, and everything seems to be working fine. However, as your application grows, you start to notice that the codebase is becoming increasingly complex and harder to maintain. This is where functional programming paradigms come in - a set of principles and techniques that can help you write more modular, composable, and maintainable code.

Why This Matters

In recent years, functional programming has gained popularity in the JavaScript and TypeScript communities. This is because functional programming provides a set of principles and techniques that can help developers write more predictable, composable, and maintainable code. In this article, we'll explore how to implement functional programming paradigms in modern TypeScript 5.5.

Background/Context

TypeScript is a statically-typed, multi-paradigm programming language developed by Microsoft. It's designed to help developers catch errors early and improve code maintainability, thus making it a popular choice for large-scale applications. Functional programming, on the other hand, is a programming paradigm that emphasizes the use of pure functions, immutability, and the avoidance of changing state.
