Deno, a new way to JavaScript
summary
A new runtime claims to replace Node by running JavaScript and TypeScript in a single ~50MB executable built on V8 and Rust, with TypeScript compiled via V8 snapshots for fast startup. Module loading uses URL imports with a local cache and dependency tree inspection, and native bindings use message-passed promises-to-futures. Security is secure-by-default sandbox with fine-grained allow flags. Demo shows a working HTTP server, filesystem file server, caching behavior, and missing pieces like TLS and debugger.
