Each homework is numbered (01, 02 etc.). Inside the numbered folder you may find two folders: fsharp and scala. The former contains implementation of a task written with F# and the latter - with Scala.
First, you need to install .NET. That is very simple - just find your OS and lines to execute here. Then you need to install Visual Studio Code, and Ionide plugin for it.
In case a task is written as script(s), you will see fsx files which you can run the following ways:
- Open folder with scripts in VS Code. Click
Ctrl + A, and thenAlt + Enter, which sends the selected text into REPL - Or run
dotnet fsi scriptname.fsxin console
Here is video example which shows both of those options: https://youtu.be/AyCYXAOFoto
If you have any questions about how to use REPL, or have problems with .net/vscode/ionide installation - let me know.
Also, you may want to read a very short F# overview. I expect it to take 30 - 60 mins at max for Scala users:
