Question

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!") }
}

Answer 1

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" );
