[det]js_call(+Term)//Emit a call to a Javascript function. The Prolog functor is the name of 
the function. The arguments are converted from Prolog to JavaScript 
using js_arg_list//1. Please 
not that Prolog functors can be quoted atom and thus the following is 
legal:
    ...
    html(script(type('text/javascript'),
         [ \js_call('x.y.z'(hello, 42))
         ]),
