What is Deno, the next-generation JavaScript runtime
Deno is a secure runtime for JavaScript and TypeScript, built on V8 and Rust. It aims to improve upon Node.js by addressing its architectural and security shortcomings. Deno offers built-in TypeScript support, enhanced security features, and a modern module system using URLs. It prioritizes developer experience with features like automatic code formatting and a built-in package manager. Deno's design emphasizes security, sandboxing code by default and requiring explicit permissions for file access, network requests, and environment variables. This makes it a safer environment for running untrusted code and building robust applications.
