Deno Js – Beginner Guide [2022]

Welcome to Deno course .
Deno is a new project created by Ryan Dahl (the inventor of Node.js) that aims to fix Node.js design mistakes.

Deno’s top features:

Security

Module system

TypeScript support out of the box

Secure by default. No file, network, or environment access, unless explicitly enabled.

Supports TypeScript out of the box.

Ships only a single executable file.

Has built–in utilities like a dependency inspector (deno info) and a code formatter (deno fmt).

Has a set of reviewed (audited) standard modules that are guaranteed to work with Deno

Has a number of companies interested in using and exploring Deno

Deno aims to be a productive and secure scripting environment for the modern programmer.

Deno will always be distributed as a single executable. Given a URL to a Deno program, it is runnable with nothing more than the 25 megabyte zipped executable. Deno explicitly takes on the role of both runtime and package manager. It uses a standard browser–compatible protocol for loading modules: URLs.

Among other things, Deno is a great replacement for utility scripts that may have been historically written with Bash or Python.

I think Deno is on the right path in order to be a better Javascript runtime than Node.js.
