I think @rsp has already posted detailed info related to Deno.

I want to put some key points here so that others can easily put their eyes on key difference:

• Language- Deno is based on RUST language - Rust is a multi-paradigm programming language focused on performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but provides memory safety without using garbage collection

• Runtime- Deno also relies on the V8 engine.

• Security — A common criticism of Node.js is that once a node app is running, it can easily access the file system or the network etc. While Deno asks user permission to allow use of resuorces like net, file system etc.

• NPM?- Deno does not rely on NPM at all, instead of this we import our libraries via the URL.

Example:

> import { serve } from "https://deno.land/std/http/server.ts";

All the library we want to use is downloaded first then cached it.

• Window Object- Good news is that now we can use the Window Object in Deno which is not available in Node.js. Window Object has much rich APIs which can help a lot in Deno for development.
• Import- Deno use ES6 import in inject the module in files.
• Typescript- Deno fully supports typescript.
