io.js vs. Yesod vs. Phalcon

io.js is a JavaScript platform built on Chrome's V8 runtime. This project began as a fork of Joyent's Node.js and is compatible with the npm ecosystem.

Yesod believes in the philosophy of making the compiler your ally, not your enemy. We use the type system to enforce as much as possible, from generating proper links, to avoiding XSS attacks, to dealing with character encoding issues. In general, if your code compiles, it works. And instead of declaring types everywhere you let the compiler figure them out for you with type inference.

Phalcon is a web framework implemented as a C extension offering high performance and lower resource consumption.
