Transcript

Deno was introduced by Ryan Dahl in 2018 during a presentation on the topic “10 things I regret about Node.js.”

What is Deno?

  • Secure by default
  • Built-in TypeScript support
  • No package manager needed (uses URLs for imports)
  • Modern runtime for JavaScript and TypeScript

Node.js vs Deno

How does Deno handle asynchronous operations?

Deno.js uses asynchronous operations heavily, relying on the same event-driven, non-blocking I/O model as Node.js. It uses promises and async/await syntax for handling asynchronous code.

Conclusions

Node is currently the most stable runtime as it enjoys support from a large community.

A great competition ...

However, lots of people believe Deno will replace Node as the newer runtime offers many benefits to developers.
