About F#

module HelloWorld

let hello = "Hello, World!"

F# is a strongly-typed, functional language that is part of Microsoft's .NET language stack.

Although F# is great for data science problems, it can elegantly handle almost every problem you throw at it.

As F# runs on the .NET runtime, you get access to the entire .NET ecosystem, including all packages on nuget.org.

Integration with existing .NET code is further simplified due to F# also allowing you to write object-oriented code.

The home page for F# is fsharp.org and a great introduction to F# can be found at the F# for fun and profit website.

I really like the ability to look at other people's solutions.

I'm working through the F# and Python tracks at the moment. Really like the ability to look at other people's solutions. I've had some helpful comments from others too.

Relaxed. Encouraging. Supportive.

I love programming, and do it both professionally and as a hobby. At work I do most javascript and typescript, but I've also done a lot of F# and C#.

Software crafter, legacy code wrestler. I help companies get things done without shooting themselves in the foot and teach others how to do it. I use F# at work for everything except production code!
Fun. Challenging. Interesting

I am a developer with a passion for learning new languages. After falling in love with functional languages, F# quickly became my favorite language.

I stumbled upon this site when I was trying to learn about functional programming and F#. Little did I know, I'd wind up becoming a contributor and learning a whole lot more than what I originally intended to. I had never contributed to an open source project before, and it's been a very rewarding experience.

Get started with the F# track. As with everything on Exercism, it's 100% free!
