• If starting out: on web, Python and Typescript will take you far. On mobile, Swift and Kotlin. On Windows/Mac, C# and Swift. You’re on your own for Linux desktop.

    • C#/.NET supports Linux quite well and there is Avalonia for UI. Also there is a cross platform trend amongst modern languages such as Kotlin/Jetpack - not that I’m too keen on this approach.

    • On the web I would stick entirely with Typescript. There are plenty of server side Typescript systems; you don’t need to resort to Python.

      Most recently I’ve been using Deno’s Fresh framework which is fantastic. Very easy to use and suitable for beginners IMO since you can start with traditional request per page & static templated responses - no complex state management.
