Deno is an innovative runtime for JavaScript, TypeScript, and WebAssembly, designed to provide a secure and efficient development experience. Created by Ryan Dahl, the original developer of Node.js, Deno was introduced in 2018 as a response to the challenges and limitations faced by developers using Node.js. This article explores the key features, architecture, and advantages of Deno, highlighting its potential impact on the JavaScript ecosystem. Overview of Deno Deno is built on the V8 JavaScript engine and is constructed using Rust, which contributes to its performance and security features. Unlike Node.js, which relies on a package manager (npm) and has a more permissive security model, Deno emphasizes security by default.
