Benchmarking programming languages and web frameworks

Koa (JavaScript)

Koa is a lightweight and expressive web framework for Node.js created by the team behind Express. It leverages JavaScript's async functions to eliminate callbacks and improve error handling. Koa provides an elegant middleware architecture that processes requests downstream and manipulates responses upstream. Unlike Express, Koa doesn't bundle any middleware in its core or provide built-in routing, emphasizing modularity and giving developers greater flexibility in their component choices.
This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.
