About

Deno is a modern JavaScript and TypeScript runtime built with security by default. TypeScript runs natively without a compile step, there are no node_modules directories, and formatting, linting, and testing tools are built in. npm packages work via the npm: specifier so most of the ecosystem is accessible. Best for scripts, edge functions, and new projects that want a cleaner setup than Node.js.
