[PLUG] Javascript on Client Side

[Rich Shepard]

   I'd like some insights from you folks who know Web applications from the
server and client ends. My friend has javascript enabled in firefox and
chrome but facebook (and another site or two) either do not recognize this
or, perhaps, are using js features not in the version installed on her
computer.

   I thought that js was a server-side only language. What does it do on the
client side? It would be nice to resolve this issue sooner rather than
later.

TIA,

Rich
