The F# programming language is like a typed Python. The F# language was carefully crafted to have the ease of a scripted language, without a run-time wait-and-see compromise. Yet, you also get instant REPL feedback. Such an expressive and agile blend is somewhat unique.
F# is multi-paradigm. It’s a functional-first language, but it also supports the object-oriented approach. It’s a .net citizen, meaning that you can mix and match anything in ILAsm. F# has pipelines to produce code that runs in browser, iOS, and Android. F# has GPU support. F# works on Linux and Windows. F# code runs on devices everywhere. F# code even runs natively on iOS (via Xamarin's AOT cross compiler).
The F# OSS community continues to innovate. For example, F# had async / await in 2007.
We were curious about how F# might have inspired C#, so we got in touch with Mads Torgersen (Mads is the MS C# Program Manager). Mads replied:
"F# is a great language for us C# designers to be around. There's a lot we can learn about how functional features are used in practice, and how to build them on the .NET platform. At the same time, I think C#'s adoption of more functional features is good for F#: it makes it a smaller leap for a .NET developer to try their hand at F# and get the full functional package."
