[Users] Advice regarding optimization and debugging

[geographika]

Along with what others have said:

<http://www.jsonlint.com/>

    * http://www.jsonlint.com/ - for validating any JSON that comes from
      a server
    * Fiddler - for rerunning Ajax calls
    * http://code.google.com/closure/ - for minifying production code
      (and as another check of code quality)
    * making sure gzip is set up on your server.
    * The ExtJS docs - http://dev.sencha.com/deploy/dev/doc
      <http://dev.sencha.com/deploy/dev/docs/>s/
      <http://dev.sencha.com/deploy/dev/docs/>
    * Also I am testing a trial version of
      http://www.illuminations-for-developers.com/product/debugger/

Plus writing:

debugger;

In JavaScript files to automatically create a breakpoint in FireFox to 
check what exactly is happening.
