BBC NEW Website

I really love the new BBC web site, I want to build similar one and I thought they were using
jquer y/JS, but they are not using it.
Then what programming language are they using?
Could anyone advise me?

Which site do you mean? Could you link to it? I see a lot of JavaScript on the BBC site.

this is a link about the new bbc home page

They wrote their own scripting library a year or so ago.

And you can download it.
