Comparing 10 programming languages. I built the same app in all of them.

Many modern programming languages have some great features like null safety, exhaustive switch statements, error handling, strong type systems, immutability, great tooling and good readability and write-ability. I couldn't decide which language I preferred so I made a TCP server that does some basic file processing in all of them. Using no dependencies where applicable. I did this using Rust, Go (or Golang), Crystal, Kotlin, Julia, Zig, Nim, Gleam, Swift and Dart. Just for fun, I gave each language a 1 to 5 score in the categories of tooling, safety, readability and ergonomics. Just btw this is an incredibly biased video so please don't take anything personally.
