Functional programming is a programming paradigm that emphasizes immutability and pure functions. It not only makes code easier to understand, test, and parallelize, but also offers improved performance. TypeScript is a statically-typed object-oriented programming language that builds on JavaScript. Although TypeScript is not a purely functional programming language, it can be used to write functional code too. 

This course is for beginners with little to no knowledge of TypeScript and functional programming. You’ll start with learning their basics and then move on to develop several projects of increasing complexity. You’ll also learn about fp-ts, a library that provides several functional programming constructs. The course covers the core functionality of fp-ts and important monads such as Option, Either, and TaskEither. 

By the end of the course, you’ll know how to apply functional programming techniques and fp-ts to new and existing TypeScript projects, and be on your way to becoming an expert in both!

Using fp-ts for Functional Programming in TypeScript

In this chapter, we wrote our first application with `fp-ts`. Along the way, we had another encounter with the Option monad and learned how to use the Either monad. We learned how to combine small functions into a larger whole. Then we talked about how the combination of functional programming and types can make our code simple to reason with and easy to change. We also learned how to add types where we needed them and how type safety can make our applications better. Moreover, our application is quite easy to extend with additional features.


Let's look at what we have learned so far in this chapter.
