Asm.js: The JavaScript Compile Target

A Strategy for i18n and Node.js

Recently I internationalized a Node/Express web application that I’ve been working on and it seems to have gone fairly well (users in multiple languages are using it happily and I’m seeing a marked increase in traffic because of it!).
