Deno Course Review: Is Deno Worth It?

The official Deno 1.0 release happened on May 13th, 2020. And guess what? There’s already a Deno course.

Deno is a modern and secure runtime for JavaScript and TypeScript. And it was created by Ryan Dahl, creator of Node.js.

Because it’s so new to the market, it’s tough to say how long it will take Deno to lift off. Or if it will at all.

But maybe you’re feeling adventurous.

Tech is always evolving.

Whether it’s a new programming language, framework or plugin, there’s always something to learn.

And it’s your job as a software developer to be ready for it. But it’s hard to know what’ll be the next hottest trend or the latest dud.

Well, Deno is no exception.

The reality is that it’s going to take a few years for Deno to catch on in the job market, if at all. That said, indulging in a new technology is delightful.

Plus because it’s so new, there aren’t a lot of resources available to learn how to use it.

But not to worry.

We found a brand new Deno course by Andrei Neagoie – Deno: The Complete Guide Zero to Mastery.

Let’s take a closer look at Deno and see why taking a Deno course might be right for you.

๐Ÿšจ We want to stress: If you’re a new developer looking for a job, Deno will not help you get hired. Consider checking out The Complete Web Developer Zero to Mastery which focuses more on in-demand skills.

Deno is a secure runtime for executing JavaScript and TypeScript securely outside of the browser. It’s a single executable file that knows how to fetch external code.

It was built using the V8 JavaScript Engine, Rust and tokio. And it’s meant to be a standalone tool for quickly scripting complex functionality.


Ryan Dahl wasn’t happy with a lot of decisions he made when creating Node.js. Because of its security and complexity flaws, Dahl wanted something better.

Deno was created as a response to Node.js.

And it has some prominent features you won’t find with Node.js. Let’s take a look.

  • JavaScript runtime, must set up tooling to use TypeScript
  • Built using V8, C++ and libuv
  • Holes in security
  • NPM library
  • Third party modules
  • Trusts scripts by default

  • JavaScript and TypeScript runtime
  • Built using V8, Rust and tokio
  • Sandbox security
  • Standard library approved by Deno contributors
  • Built-in tooling includes testing, formatting, filewatchers w/bundling, etc.
  • Must manually authorize scripts

โ— But Node.js is an industry standard.

Yes, it is. And rest assured, Node.js isn’t going anywhere.

But with tech, it’s always better to be ahead of the curve than trying to catch up.

Luckily, Andrei Neagoie has a solution for that: Deno: The Complete Guide Zero to Mastery video course.


Deno: The Complete Guide Zero to Mastery introduces and immerses you in all things Deno. This project-based video course covers everything from the shortcomings of Node.js to advanced concepts in Deno.

While learning Deno fundamentals, it provides a walkthrough from start to finish of releasing a professional Deno project.

Bonus: You’ll get access to the full master project code to use in your portfolio.

This Deno course covers how to:
