Which programming language is better to back-end and why ?

Answer 1

Achraf Battou Out of those options you listed JavaScript is probably the best for speed and reliability (or TypeScript which compiles to JavaScript and is more reliable). Yet the language that probably does the best job for speed and reliability is Rust. It's very fast, reliable and secure. I can recommend you to use the Actix-web framework which is written in Rust and one of the fastest web frameworks that exist.
