Deno 1.0 – “Deno is a web browser for command-line scripts”
JAXenter: Hi Ryan, nearly two years ago you began developing Deno, which started out with the idea of evolving into an alternative to Node, building upon different concepts. Now, with v1 just around the corner, what would you say is the main difference between Deno and Node?
Deno had to pursue ideas that were incompatible with the existing ecosystem.
Ryan Dahl: Deno uses a radically simple module system where modules and URLs are in one-to-one correspondence. Furthermore, Deno can execute TypeScript code out of the box. These two features have the effect of greatly simplifying the developer workflow. Deno is stricter with security than Node; by default, scripts are run in a secure sandbox without access to the operating system – users can opt in conditionally to provide further functionality – this is to correspond to the browser security model where websites ask for permission to access the camera or location info. Generally, Deno acts more like a web browser – it is, in essence, a web browser for command-line scripts.
