Deno is a runtime environment for JavaScript and TypeScript. Since it’s built to improve upon the earlier version of Node.js, Deno offers significant upgrades to improve security and real-world performance while offering developers modern instrumentation.

In this course, you’ll discover Deno’s main features and explore its similarities and differences in relation with Node.js. You’ll then be led through a series of detailed project examples and practical code exercises to master its runtime.

By the end of the course, you’ll be ready to create professional, highly performant JavaScript or TypeScript applications with Deno.

Master the Deno JavaScript Runtime

## Create an HTTP server with the standard library

Deno offers an `http` module for HTTP client and server implementations among its standard libraries. Creating an HTTP server is very easy with this module and is possible with just a few lines of code.

The code widget below shows an HTTP server example using Deno's standard library. The script listens to port 5400 and returns the string `I am a DENO server 🦕` as a response when it receives a request.
