Node.js

JavaScript на сервере.

Node.js runs JavaScript outside the browser: on servers, in command-line tools and in the build tools you use every day. This track takes you from your first node command to a tested, secure JSON API: modern ES modules and npm, the event loop and worker threads, files and streams, HTTP servers with node:http and Express 5, validation, errors and logging, the built-in test runner, TypeScript with no build step, and deployment.

You already know JavaScript. Here you learn to run it where the data lives.
