DenoJS is there to replace NodeJS. Or, at least, it has the goal to do so and to fix NodeJS’ biggest flaws. It’s by the same creator (Ryan Dahl) and it comes with some pretty interesting built-in features like TypeScript support and more. Let’s take a first look at Deno, explore it’s key features and find out if you should make the switch.

  1. Thanks Max. Are you going to create another amazing course and launch it on Udemy? I'm sure there's thousands of people who know you that will be thinking exactly the same thing. It's a shame that more people aren't looking at Rust as an alternative to NodeJS as it's popularity may win our vote for you to create a Rust course 😀

  2. Besides out of the box typescript support, I don't see any reason to switch to Deno. On top of that the Node / Express code you showed (for creating a web server), looks a lot cleaner than the Deno approach.

  3. An important update, Deno will NOT USE TYPESCRIPT internally anymore. https://docs.google.com/document/u/0/d/1_WvwHl7BXUPmoiSeD8G83JmS8ypsTPqed4Btkqkn_-4/mobilebasic

  4. Developers: Deno will replace Node.js
    Me: Mathafaca, I just learned Node.js after a hard struggle of two years.

  5. Hi Max,
    Hope you are doing great
    Can you please make "Deno JS – The Complete Guide" Just like
    NodeJS – The Complete Guide (incl. MVC, REST APIs, GraphQL)

  6. Just keep in mind that deno uses the term "modules" instead of "packages" so it doesn't get confused with node packages.

  7. Being a typescript guy, I straight away accept deno and reject both JavaScript and nodejs. It's time we should move away with this awful language called JavaScript. Deno is the first step towards this direction.

  8. i am sooo tired of all of the new things, frameworks, etc that keep on appearing.it's great that people get bored with what we have… let's focus on creating useful experiences instead of relearning frameworks and tools that do 99% the same things, every 3 months

  9. Short answer no. Long answer noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooot yet.
    You adorable js devs chance frameworks/libs more then ya undies 🙂

  10. deno is just the same node.js v8 engine + typescript compiler built in rust into one executable file. It also uses es6 imports / exports + has a built formatter + bundler -> in the end it can also replace webpack for some (just like snowpack / pika). The less tooling to use the better imho. Try deno –version + deno -h. It is node.js after all

  11. If my code has dependent permissions, and third-party modules also rely on permissions, the permissions I gave can also be used by third parties, how to avoid risks

  12. Without npm install how can we manage packages version?, it sounds kind of messy to only have those references at the code level.

  13. What is deno? What is deno? Here are 3 changes. Btw, it’s so new, doesn’t have nomenclature nor backwards compatibility….so, thanks for wasting our time. This sounds more like an ego project because inventor was pissed people picked on node for NPM

  14. First man… Whats that new thing similar to node.js……… second man answers…. Den-o…. First man oh I thought you'd know !!! 🤣🤣🤣
