The Recipe for Node.js

The reactor pattern and libuv and the basic building blocks of Node.js but we need the following three other components to build the full platform:

• A set of bindings responsible for wrapping and exposing libuv and other low-level functionality to JavaScript.
• V8, the JavaScript engine originally developed by Google for the Chrome browser. This is one of the reasons why Node.js is so fast and efficient. V8 is acclaimed for its revolutionary design, its speed, and for its efficient memory management.
• A core JavaScript library (called node-core) that implements the high-level Node.js API
