Deno was created in 2018 by Ryan Dahl, the original creator of Node.js. It was developed to address certain design mistakes and security issues he identified in Node.js. Dahl aimed to create a more secure and modern runtime by integrating TypeScript support, improving module management, and enforcing stricter security measures.
Deno
Deno is a modern runtime for JavaScript and TypeScript, built on the V8 JavaScript engine and developed by the creator of Node.js, Ryan Dahl. It is designed to improve security, support TypeScript out of the box, and offer a more streamlined standard library. Deno aims to provide a secure environment by default, requiring explicit permission for file, network, and environment access.

About Deno
Deno's strengths include built-in TypeScript support, enhanced security through explicit permission control, and a comprehensive standard library. Its weaknesses involve a smaller ecosystem compared to Node.js and less community adoption. Competitors include Node.js, which dominates the server-side JavaScript environment, and other runtimes like Bun.
