  "summary": "Secure-by-default JavaScript and TypeScript runtime from Deno Land with web-standard APIs, built-in tooling and an optional hosted Deploy service",
  "description": "Deno is a JavaScript and TypeScript runtime created by Node.js author Ryan Dahl and developed by Deno Land. It runs on V8 with a Rust core, executes TypeScript natively, and restricts file, network and environment access unless permissions are granted on the command line. The binary bundles a formatter, linter, test runner, documentation generator and a compiler that produces standalone executables.\n\nDeno favors web-standard APIs (`fetch`, Web Streams, Web Crypto) so code can move between browser, server and edge environments, and since version 2 it supports npm packages and most Node.js APIs for compatibility. Deno Land also operates Deno Deploy, a hosted edge platform, and the JSR package registry. The runtime is free and MIT-licensed; Deploy is a commercial service with a free tier. Limitations include a smaller ecosystem of Deno-first libraries, occasional gaps in Node compatibility, and permission flags that add friction for scripts expecting unrestricted access.",
  "capabilities": ["TypeScript execution without configuration", "Permission model for file, network and environment access", "Built-in formatter, linter, test runner and doc generator", "npm and Node.js compatibility layer", "Compile scripts to standalone executables", "JSR package registry integration"],
  "workflows": ["Write a TypeScript script with explicit permissions and run it as a cron job", "Deploy an edge function to Deno Deploy", "Compile a CLI into a single executable for distribution"],
  "advantages": ["Security-oriented defaults", "Web-standard APIs shared with browsers", "Tooling bundled in one binary"],
  "limitations": ["Smaller Deno-first ecosystem than npm", "Node compatibility is good but not exhaustive", "Deploy is a proprietary hosted service"],
  "prerequisites": ["macOS, Linux or Windows; install script, Homebrew or Cargo"],
  "audiences": ["TypeScript developers", "Teams building edge or serverless functions", "Developers who value sandboxed scripting"],
  "alternatives": ["nodejs", "bun"],
  "comparison_notes": "Node.js has the broadest package compatibility and the longest track record; Deno trades some of that for a permission model and web-standard APIs. Bun shares Deno's goal of a batteries-included runtime but prioritizes Node compatibility and raw speed over sandboxing.",
