Browser Version Control

There are different browsers and versions out there. Thus you, the programmer, do not know what JavaScript capabilities the user has.

This is the most common way to avoid any scripting error.

Web console with node.js
Continuing with my experiments of node.js, this time I want to create a Web console. The idea is simple. I want to send a few command to the server and I display the output inside the browser. I can do it entirely with PHP but I want to send the output to the browser as fast as they appear without waiting for the end of the command.

Conditional Statements
