I currently am an avid user of Crystal. I fell in love with its syntax and network wrappers. Setting up a TCP Server is super simple, same for storing clients in an Hash, etc. Also the JSON.parse/.to_json methods they have are awesome. It makes reading/outputting JSON data a breeze.
I’ve heard julia is more of a language geared towards “scientific computing”. But I was looking at the docs and it seems much more than that, haha!
all general purpose language can do what a game server does in terms of TCP, JSON parsing and all, maybe a more important criteria falls on how the backed of that server integrates with what runs the game.
