 The routers are really fast and smart. Not using linear loops. Fast. • Multi-runtime
 Works on Cloud fl are Workers, Fastly Compute@Edge, Deno, Bun, Lagon, or Node.js. The same code runs on all platforms. • Batteries Included
 Hono has built-in middleware, custom middleware, and third-party middleware. Batteries included. • Delightful DX
 First-class TypeScript support. Now, we've got "Types". • Small
 About 20kB. Zero-dependencies. Using only Web Standard API.  3FH&YQ3PVUFS
