web service

Go (also called Golang) is a favorite language for building back-end services: it compiles to a single fast binary, it handles many requests at the same time without extra libraries, and its standard library already contains a production-grade web server. Since Go 1.22, the built-in router http.ServeMux also understands HTTP methods and URL wildcards such as GET /api/books/{id}, so for many projects you no longer need a framework like Gin, Echo or Chi.
