29. What is the difference between Express and Koa

In short, both are web frameworks for Node.js but Koa is considered more lightweight and flexible compared to Express. Koa uses generator functions which allows for easier and cleaner asynchronous code, while Express uses callbacks. Koa also has a simpler error-handling mechanism and enables better middleware composition. However, Express has a larger community and more plugins available. Ultimately, it depends on your project's needs and personal preferences.
