Q: Is Deno going to replace Node.js?
A: It could. If it does, it will be one of the coming-to-age events for the Rust language for server-side applications. The same way Twitter made the Ruby language a legitimate choice for web apps almost 15 years ago.
Q: One of the great selling point of Deno is that it is written in Rust. Can I use Rust to enhance and extend Deno for my apps?
