Deno

Deno is an open-source runtime for TypeScript and JavaScript, designed for modern programming with built-in development tools, robust platform APIs, and native support for TypeScript and JSX. It offers productivity, security, and performance, allowing developers to write type-safe code without complex build systems, enabling native support for JSX and TSX, and embracing bleeding-edge ECMAScript features.

Deno is built on web standards, actively participating in advancing web technologies, and providing consistent code across browser and backend environments. Notably, Deno enhances security by preventing supply chain attacks, restricting access by default to ensure controlled file system.
