Node.js - the core

Node is a programming environment implemented on Google's V8 JavaScript engine. Node is well-suited for implementing server applications that are primarily I/O-bound rather than compute-bound.
It supports a variety of network protocols such as HTTP and TCP.

While Node's primary programming language is JavaScript, applications can be extended with code written in C and C++. It has excellent performance characteristics, in part because its performance critical underpinnings are written in C/C++. Node enables web development where the same familiar programming language, JavaScript, is used for the client and server.

Making effective use of any programming environment requires a certain amount of familiarity with it's provided libraries. Imagine trying to write a Java application without knowing what is available in the
java. and javax. packages. Rather than “packages”, Node has “modules”. Provided modules are referred to as the “core modules”.

This talk begins with an overview of Node. It then provides a review of the core modules including examples of commonly used functions. Armed with this knowledge, you'll be ready to begin writing Node applications.
