Chapter 1. C# and F# Data Structures

In this chapter, I’ll compare and contrast various data structures from F# and C# programming languages. F# is a powerful multiparadigm language that supports imperative, object-oriented, and functional programming. C# is a multiparadigm language with more of a focus on imperative and object-oriented programming. A C# program usually consists of statements to change the program’s state. An imperative language describes how to finish a task with exact steps. A functional-first language, like F#, is more declarative, describing what the program should accomplish.

One example of a programming language adopting functional programming is the C# version 3.0 introduction of LINQ (Language INtegrated Query). The growing ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
