What is Deno?
Deno is an open-source JavaScript runtime designed for the modern web, offering a secure and efficient environment for developing web applications. It natively supports TypeScript, JSX, and modern ECMAScript features without requiring additional configuration. Deno integrates seamlessly with npm and Node.js packages, allowing developers to leverage existing ecosystems while benefiting from Deno's built-in tooling, including a linter, test runner, code formatter, and the ability to create standalone executables.
Deno prioritizes security by default, restricting file, network, and environment access unless explicitly enabled, which helps prevent supply chain attacks. It's built on web standards, promoting consistent code across browser and backend environments. Deno also offers high-performance networking and is optimized for cloud deployments, including its own lightning-fast Deno Deploy platform. Deno Deploy provides a comprehensive platform for deploying JavaScript and TypeScript applications, featuring automatic GitHub deployments, custom builds, preview domains, and a data layer with managed KV stores and database integration. It boasts faster cold starts and elastic scalability, running code in lightweight V8 isolates.
