I am also searching for similar kind of sorting. Kindly give me an idea how do we implement this in a class using a private method.

I tried to make work the array like you have, and I can’t; instead of, I made an array of JSON objects, like this:

var maxSpeed = [
{vehicle:'car', velocity:300},
{vehicle:'bike',velocity:60},
{vehicle:'motorbike',velocity:200},
{vehicle:'airplane', velocity:1000},
{vehicle:'helicopter',velocity:400},
{vehicle:'rocket', velocity:8*60*60}
];

then, I used a sorting function that sort the array using the velocity property of the objects.

function SortByVelocity(a,b)
{ return a.velocity - b.velocity; }

maxSpeed.sort(SortByVelocity);

and it’s works very fine!

I wrote a sorter for arrays of objects a while ago that also comes to mind:

var obj = {
car: 300, bike:60, motorbike:200, airplane:1000,
helicopter: 500, rocket: 8*60*60
};

console.log(sortObj(obj,1));
