> Deno is the secure JavaScript/TypeScript runtime from the creator of Node.js — TypeScript runs natively, permissions are explicit, and the formatter, linter and test runner are built in…

Deno is a modern, secure runtime for JavaScript and TypeScript built on V8 and Rust by Ryan Dahl, the original creator of Node.js. It executes TypeScript natively with no build step or tsconfig ceremony, ships a complete toolchain in one binary — formatter, linter, test runner, compiler, and package management — and is secure by default: scripts cannot touch the file system, network, or environment unless you grant explicit permission flags. Deno 2.x adds full Node.js and npm compatibility, so existing packages and even whole Node projects run under it, plus a standard library, workspaces, and the JSR package registry. This download is the official Windows x64 build from the Deno GitHub releases.

## Installation

1. **Download and extract the ZIP** — Download Deno from the official GitHub link on this page and extract deno.exe to a folder on your PATH (e.g. C:\Tools\deno).
2. **Verify the install** — Open a terminal and run deno --version. Then try a script: deno run main.ts — TypeScript works with no extra setup.
3. **Grant permissions as needed** — Deno asks for nothing by default. Add flags only for what your script needs: --allow-net for network, --allow-read for files, or -A for everything in trusted local scripts.

## Editorial verdict

Deno is what Node.js looks like with ten years of hindsight applied. Ryan Dahl's runtime fixes his famous list of regrets: TypeScript is a first-class citizen with zero configuration — you write .ts files and run them, no webpack, no ts-node, no build step — and the chaos of node_modules is optional now that Deno 2 speaks npm fluently while preferring clean URL and JSR imports. The single executable also replaces half your devDependencies: deno fmt, deno lint, deno test, deno check and deno compile (which bundles a script into a standalone .exe) are all built in, fast, and configured by convention rather than by five competing config files.

The security model is the other headline: a Deno script runs with no file, network, or environment access until you pass explicit --allow flags, which turns 'curl | sudo' style supply-chain roulette into a reviewable decision. In practice on Windows the binary is small, starts fast, and runs existing Node projects surprisingly well. The caveats are ecosystem-shaped: some older npm packages with exotic native bindings still assume Node internals, corporate tooling and tutorials default to Node, and the permission prompts, while principled, will annoy you during the first week of prototyping until -A becomes muscle memory for local work. For new TypeScript projects especially, Deno is the cleaner daily driver.

### Strengths

- Native TypeScript with no build step, config files, or transpiler — deno run file.ts just works, with full type checking built in.
- Secure by default: file, network, and environment access require explicit permission flags, a real defense for scripts and tooling.
- Complete built-in toolchain — formatter, linter, test runner, bundler, and deno compile for standalone executables — in a single small binary.
- Deno 2 runs Node.js code and npm packages, so most existing projects migrate without a rewrite, and workspaces are supported.
- Modern web-standard APIs (fetch, WebSocket, streams) work the same on the server as in the browser, reducing API déjà vu.

### Trade-offs

- A minority of npm packages with deep Node-specific or native-addon assumptions still misbehave; large legacy Node codebases need testing before switching.
- The ecosystem's tutorials, hosting guides, and corporate standards still default to Node, so you will occasionally translate instructions.
- Permission flags add friction during rapid prototyping — you will grant -A locally more often than the security model ideally wants.

## FAQ

**Is Deno free?**

Yes — Deno is open source under the MIT license. The runtime and toolchain are completely free; Deno Land sells optional cloud hosting (Deno Deploy) separately.

**Can Deno run my Node.js project?**

Usually, yes. Deno 2.x supports npm packages, package.json, and Node's built-in modules, and adds workspaces. Projects relying on exotic native addons are the main exception — test before committing.

**Do I still need to install TypeScript separately?**

No. TypeScript support is built into the runtime. Deno type-checks and executes .ts files directly with no tsconfig or build step required.

**How do I install Deno on Windows?**

Download the ZIP from this page's official GitHub link, extract deno.exe to any folder, add that folder to your PATH, and run deno --version to confirm.

**Why does Deno keep asking for permissions?**

That is its security model: scripts start with no access. Grant exactly what is needed (--allow-net, --allow-read=./data) or use -A for scripts you fully trust.
