Deno is the JavaScript and TypeScript runtime created by Ryan Dahl in 2018 to address several limitations of Node.js, including security concerns, TypeScript integration, and the complexity of npm tooling. It offers secure defaults, native TypeScript support, and a cohesive standard library, making it a streamlined choice for developers. The release of Deno 2.x in 2024 added backward compatibility with npm packages and introduced the JavaScript Registry (JSR), enhancing its utility as a curated package ecosystem. These features render Deno particularly effective for edge functions, CLI scripts, and serverless applications, where its efficient security model and rapid startup times offer distinct advantages.
