Native JSON support coming to your browser!

Finally! This will greatly improve client performance for Golemizer (and next project not yet ready to talk about)!

Communication between your browser and Golemizer's server is done using a web service sending JSON data. To parse the data received in JSON format, the javascript function eval() is used. Native support of JSON will make the parsing of this data much faster than using the eval() function (without talking about other disadvantages but eval() was still faster than a custom built json parser).

Less client-side lag!
