very true :) ... so in summary ... it is not possible to hide such code from the users ... all JavaScript and HTML code needs to be downloaded to the client since the browser needs to parse and process it ... once downloaded (to the clients filesystem) it is just some clicks away to be viewed, copied, anaylized, locally changed or whatever ... those things are 'open source' per se, even when it might be licensed or soemthing like that ... it is not avoidable to have it viewed or stored somewhere. in case you need to hide things ... then you need to do that things at the server.
kind regards
