Browser Version Control

There are different browsers and versions out there. Thus you, the programmer, do not know what JavaScript capabilities the user has. Insuring that the scripts you write run in most users browsers can be done in a few different ways.One way is to use JavaScript to check which browser they are using, and then program accordingly. This is the most common way to avoid any scripting error.

OK we can do it flushing the output in the server but this solution normally crashes if we keep the application open for a long time. WebSockets again to the rescue. If we need a cross-browser implementation we need the library. Let's start.
