Deno - Modern JavaScript/TypeScript Runtime

Deno is a modern, secure runtime for JavaScript and TypeScript built on web standards. Created by Ryan Dahl (the original creator of Node.js), Deno addresses many of Node.js's architectural challenges while adding powerful new features.

Key Features:

• Secure by Default: No file system, network, or environment access unless explicitly granted
• TypeScript First: Native TypeScript support with zero configuration
• Web Standards: Built on web APIs that work the same in browser and server
• Complete Tooling: Built-in test runner, formatter, linter, and documentation generator
• Single Binary: No external dependencies, downloads in seconds
• Node Compatibility: Seamless npm package and Node.js built-in module support
• Modern Architecture: Based on V8, libuv, and Rust with async/await
• Enterprise Ready: Production deployments at Netflix, GitHub, Supabase, Stripe, Slack, and 400k+ users

Why Deno:

• Security: Sandboxed by default, explicit permissions
• Developer Experience: Zero-config TypeScript, built-in tools
• Web Standards: Future-proof APIs that match the browser
• Performance: Fast startup, efficient execution
• Simplicity: One binary, no complex dependency management
