I like the Deno runtime approach more than Node, but that's another issue. I find JS/TS is pretty great for ETL and input data validation and transformation where the flexibility of the language and io streams lend themselves to that work. Not to mention when you need a slightly different script.

I also like the expressiveness and productivity I get out of it. Though many of my issues with C# comes down to the culture in practice more than the language.

C# is better when you have more firm constraints and the coffee will be longer lived and worth the complexity. It's just the difference between a script and a full program/application with all that involved in the Net space.

My point was mostly that. Net is still pretty good for things in Linux even without a blessed, official desktop UI framework.
