Sort an array object descending orders (max length first.)

Question

By using this I can able to get the ascending order how can I get the reverse order max length first.?

{
    category: [ 
        { name: "Cat1", elements : [ 
            { name: name, id: id } ] 
        },
        { name: "Cat2", elements : [ 
            { name: name, id: id },
            { name: name, id: id },
            { name: name, id: id } ] 
        }, 
        { name: "Cat3", elements : [ 
            { name: name, id: id },
            { name: name, id: id } ] 
        }
    ]
}

My expected result is:

{
    category: [ 
        { name: "Cat1", elements : [ 
            { name: name, id: id },
            { name: name, id: id },
            { name: name, id: id } ] 
        },
        { name: "Cat2", elements : [ 
            { name: name, id: id },
            { name: name, id: id } ] 
        }, 
        { name: "Cat3", elements : [ 
            { name: name, id: id } ] 
        }
    ]
}

This is my sort:

var sorted_categories = original.category.sort(function (one, other) {
   return one.elements.length - other.elements.length;
});

I want reverse result from this question:

Have you tried doing `return other.elements.length - one.elements.length`? — palaѕн, Mar 25 '18 at 16:07

 array = array.reverse();

Just reverse the array?
