Book Description

Get started with F# and explore functional programming paradigm with data structures and algorithms

  • Design data structures and algorithms in F# to tackle complex computing problems
  • Understand functional programming with examples and easy-to-follow code samples in F#
  • Provides a learning roadmap of the F# ecosystem with succinct illustrations

In Detail

F# is a multi-paradigm programming language that encompasses object-oriented, imperative, and functional programming language properties. The F# functional programming language enables developers to write simple code to solve complex problems.

Starting with the fundamental concepts of F# and functional programming, this book will walk you through basic problems, helping you to write functional and maintainable code. Using easy-to-understand examples, you will learn how to design data structures and algorithms in F# and apply these concepts in real-life projects. The book will cover built-in data structures and take you through enumerations and sequences. You will gain knowledge about stacks, graph-related algorithms, and implementations of binary trees. Next, you will understand the custom functional implementation of a queue, review sets and maps, and explore the implementation of a vector. Finally, you will find resources and references that will give you a comprehensive overview of F# ecosystem, helping you to go beyond the fundamentals.

What You Will Learn

  • Familiarize yourself with the functional programming nature of F# and explore its fundamentals
  • Utilize data structures available in F# and apply recursion and lazy evaluation
  • Gain insights into functional programming paradigms; dissect F# code and analyze code available in community projects
  • Build abstract data structures and utilize powerful optimization techniques such as memoization
  • Explore and test built-in F# bespoke data structures and algorithms
  • Become resourceful and learn how to easily reuse libraries contributed by the C# and F# community
  • Understand the trade-offs in selecting purely functional (persistent) over mutable data structures
  • Implement custom ADT (Abstract Data Type), and discover parallel programming and asynchrony within F#
