You can migrate off deno in a single day. It's not a big deal.
Node only has experimental permissions support (making it not as good for local scripts), and no WebGPU (though you can import dawn wrapper). Deno desktop is way ahead of anything available for Node.
what other runtime has runtime security features?
Exactly. Probably an hour if you just tell your model of choice to do it for you and implement a logical testing framework.
And this is why deno is exiting.
There's no business here anymore.
Exactly that. I am really surprised by the amount of comments with this huge sentiment and doom mongering. These days it’s really not a big deal. Million lines of deno based ts is not a problem because pretty much any functionality provided to deno is available for node as well. You probably can migrate off much of the external deps without much hassle. You can even migrate to different language ecosystem altogether like others have mentioned in comments.
