Over the past few years, the server-side JavaScript world, once dominated solely by Node.js, has been diversifying. With the emergence of Deno, serious discussions have begun about performance, security, and module management. So, which do you think has more potential for growth? Is it Node.js’s maturity and deep ecosystem, or Deno’s modern architecture and simplified tools? In particular, which approach do you think will hold up better in the long run when it comes to security and isolation?
Which one is more efficient: Node.js or Deno?

If Deno's security model—the permission system and its default isolation—looks way more modern than Node.js's "everything is open by default" approach, is it even possible for Node.js to adapt to Deno in this regard? Or is it already too risky to change because of the size of its ecosystem?
