Mastering F#

By: Alfonso García-Caro Núñez, Suhaib Fahad

Overview of this book

F# is a multi-paradigm programming language that encompasses object-oriented, imperative, and functional programming language properties. Now adopted in a wide range of application areas and is supported both by industry-leading companies who provide professional tools and by an active open community, F# is rapidly gaining popularity as it emerges in digital music advertising, creating music-focused ads for Spotify, Pandora, Shazam, and anywhere on the web. This book will guide you through the basics and will then help you master F#. The book starts by explaining how to use F# with Visual Studio, file ordering, and the differences between F# and C# in terms of usage. It moves on to explain the functional core of F# such as data types, type declarations, immutability, strong type interference, pattern matching, records, F# data structures, sequence expressions, and lazy evaluation. Next, the book takes you through imperative and asynchronous programming, F# type providers, applications, and testing in F#. Finally, we look into using F# with distributed programming and using F# as a suitable language for data science. In short, this book will help you learn F# for real-world applications and increase your productivity with functional programming.

Summary


In this chapter, we were able to go through the main collections in the FSharp.Core library, such as lazy sequences, arrays, lists, maps, and sets; learned the difference between them in terms of mutability and memory and computation efficiency. We also saw how to use the functions in their respective modules to easily manipulate them.

After that, we worked with some advanced data structures that we coded ourselves, such as binary trees or balanced red-black trees. In the next chapter, we will go through the imperative constructs present in F#, and we will compare them with those in C#.
