🆚 Koa vs. Ruby on Rails

Koa is an expressive HTTP middleware framework for Node.js using ES2017 async functions.

Designed by the team behind Express, it offers a modular architecture, allowing developers to compose middleware functions for routing, error handling, and context management, providing fine-grained control over the request-response cycle.

Ruby on Rails is a full-stack web application framework that provides the tools needed to build database-driven applications using the Model-View-Controller (MVC) pattern.

It emphasizes a standardized project structure and naming, follows DRY ("don't repeat yourself") and "convention over configuration" principles, includes the Active Record ORM for database interaction, a built-in asset pipeline for managing CSS and JavaScript, and an integrated testing framework.
