title: Javascript Logging
body: <p>This is a noob question.</p>
  
  <p>What if I want to add logging to the java script application, which is running in a browser (IE, FF, etc.) ? As I understand I can not save log files in the client host. So, I have only two options: display my logging information in a new browser window (like "blackbird") or send the logging to the server.</p>
  
  <p>Is it correct? What kind of logging do they usually use?</p>
