Not bad eh?!

This Deno course will not only teach you the basics of Deno but also the latest features, advanced features, ecosystem, and tools, as well as show you how to actually use of all these to build professional scale apps that most tutorials shy away from.

We believe that Deno is the future and the early investment now by those who are early adopters, will pay off greatly in the future.

Imagine learning Node.js or React when they first came out. Imagine the advantage you would have had. We are excited about Deno and you should be too because it will change the JavaScript world over the next couple of years.

Here are 3 reasons why this course is unlike anything out there:

  1. You will build the biggest (and coolest) project you will find using Deno.

    We will be using best practices where we consider performance, scalability and security to build a production ready space launch system app 🚀. Let’s just say... we don’t shy away from the advanced topics.

  2. Learn Deno from the best.

    This course is taught by Adam and Andrei, two Senior Developers who have actually worked on massive projects for some of the top tech companies in the world.

    Adam has been working as a tech lead for backend systems for top companies with revenues exceeding $50 billion, including on projects like Tesla Power Wall and Blackberry. He is also an official Deno contributor.

    Andrei is a Senior Developer turned Instructor. Andrei has worked on projects for large IPO'd tech companies in both Silicon Valley and Toronto. Thousands of students from around the world have now taken his courses and many are now working at places like Google, Amazon and Tesla.

    By having both of them teach you, you'll get to see different perspectives.

    We also make it fun and as if we are working at a company together and you're learning from 2 Senior Developers.

  3. This course will be constantly evolving and updated as the landscape changes. As the Deno ecosystem evolves, this course will be updated with new lectures, resources, and the latest Deno best practices.

So will Deno replace Node? Nobody can predict the future... but we are willing to bet that those who invest their time into learning Deno will reap the benefits in the coming years.

Andrei is a great teacher. Very enthusiastic and he knows his stuff. I have a lot of his courses and they are all great. This one isn't an exception. If you want to work with Deno and create great apps, this is the course for you!

Nico Alvarez

Amazing course, just like the other courses from Andrei. Nice, short explanations, uses real-life examples and the student gets to work on real projects. All in all a great Deno course. Keep the good content coming, Andrei! :)

Nico Alvarez

It is amazing. I would definitely recommend. Everyone knows how good Andrei is but Adam Odziemkowski is at the least as good as Andrei. I don't think that you will be able to find a better course on Deno.


Adam explains things beautifully and gives detailed responses to any queries that you have. I would blindly take any course that he creates in the future. Andrei as usual is top notch. Highly recommended.

Yes! We have high quality subtitles in 11 different languages: English, Spanish, French, German, Dutch, Romanian, Arabic, Hindi, Portuguese, Indonesian, and Japanese.
