Deno 2
summary
Deno 2 ships as a single-file runtime with built-in linter, formatter, test runner and type checker, and it runs existing npm apps (created a Next.js app; node_modules ~300 MB). It shows secure-by-default permission prompts for FS and env, supports HTTP imports and a new registry JSR with autogenerated docs, and can publish TypeScript packages directly. It builds self-contained binaries via Deno compile (cross-compile to x86_64‑pc‑windows-msvc demonstrated) and manages deps with Deno install / add / remove; Jupyter notebooks and Observable Plot demos run live.
