[jQuery] chaining and functions

[jQuery] chaining and functions


Hi, another starter question:
I do not understand why
$('#content').empty().append("<b>hello</b>");
works, and this works
$('#content').empty().append(makeContent());
function makeContent(){
        return "<b>hello</b>";
        };
and this
$('#content').empty().append( function() { return "<b>hello</b>" } );
does not produce any output?
thanks, Jan Vandorpe
