For example, can I do this?:

{ 

   a: b: c: d: 1,

   e: 2,

   geh: function() { alert(Hi!) }

}

EDIT:
Is there some way I can avoid doing this?:

{ 

   a: 1,

   b: 1,

   c: 1,

   d: 1,

   e: 2,

   geh: function() { alert(Hi!) }

}

You could set a line of equality between various properties:

var foo = {};

foo.a = foo.b = foo.c = Hello;

Or you could just create a method that does the mass-assignment for you:

var foo = {

    setValue: function( props, value ) {

        while ( props.length ) this[ props.pop() ] = value;

    }

}



foo.setValue( [ a, b, c ] , Foo );
