F# got mentioned already but I would like to add another vote to it. C# is the first choice for most people when building desktop apps for Windows but F# works exceptionally well too. There is a small but robust community and there are a ton of libraries/tools that you can hook into via .NET.

I second this. Also the F# implementation was multiplatform from the beginning and VS Code tooling is available on Mac and Linux.

I code mainly in C# but I as F# for its REPL for some data manipulation tasks.
