Deno adoption guide: Overview, examples, and alternatives

Deno is a JavaScript, TypeScript, and WebAssembly runtime designed to address some of the shortcomings of Node.js, particularly focusing on security, ease of use, and modern development practices. Created by Ryan Dahl, the same developer behind Node.js, Deno improves upon its predecessor by incorporating a secure-by-default approach, inbuilt TypeScript support, and a streamlined module system that uses ECMAScript modules. It features a single-executable runtime built on Rust and the V8 engine, offering efficient memory management and performance. Deno also includes advanced features like top-level await, simplified dependency management with URL imports, and enhanced permissions control for increased security. Despite a smaller community compared to Node.js, Deno's growing ecosystem, comprehensive documentation, and modern tooling make it an attractive option for projects prioritizing security and modern development standards. It is particularly suitable for API development, full-stack development, and scenarios requiring secure runtime environments. However, developers deeply embedded in the Node.js ecosystem may face a learning curve when transitioning to Deno, although its robust documentation aims to facilitate this process.
