Best backend language to learn

• deno

  448 92,907 9.9 Rust

  A modern runtime for JavaScript and TypeScript.

  

Personally, I love TypeScript. It's my "go-to" language at work, and it's the most useful language to know when it comes to web development since JavaScript has a monopoly on the browser. For server-side programming, Deno is really fun to use.

• Nest

  312 64,263 9.9 TypeScript

  A progressive Node.js framework for building efficient, scalable, and enterprise-grade server-side applications with TypeScript/JavaScript 🚀

  

The use of Javascript/Typescript in the backend is growing in popularity and I love the fact that you can share code between the frontend and backend. I'am currently working with nestjs which is based on NodeJs, and I really like it so far. One thing to note when working with Javascript/Typescript is that the language was initially not designed to support object-orientation. For example, while Typescript does support the definition and implementation of interfaces, those interfaces are only used for type safety and can not be used e.g. in an instanceof check. Another disadvantage of JS/TS in my opinion is the way code is loaded/packaged, here I prefer most other languages which make use of classloaders, packages, namespaces. The type-system of Typescript is very sophisticated and flexible, which supports the type safety of strictly typed languages and the flexibility of non typed languages. When working with web applications, you won't come around learning Javascript at least for the frontend, so implementing your backend in the same language is more intuitive for beginners.
