Question

I have four variables of type integer –

var tip_1, tip_2, tip_3, tip_4;

The value of these variables are getting fill by some other logic which is always between 1 to 10. I need to maintain a hash with variable name as “key” and value as “value” by following these rules –

1. The variable with MAX value should be the first element in the hash and so on. e.g.
   if tip_1 = 4, tip_2 = 1, tip_3 = 2, tip_4 = 10 then hash should be something like,
   Hash = {tip_4, 10} {tip_1, 4} {tip_3, 2} {tip_1, 1}

2. In case of tie following order should be considered –
   tip_1 > tip_2 > tip_3 > tip_4;

Answer 1

You can always build your custom objects to retain all information instead of encoding them in indices. Makes sorting easier too.

function Tip(type, value) {
    this.type = type;
    this.value = value;
}

var tips = [];

tips.push(new Tip(3, 4));
tips.push(new Tip(2, 4));
tips.push(new Tip(1, 3));
tips.push(new Tip(4, 10));

tips.sort(function(a, b) {
    // sort first by value, and if equal, then by type (index)
    return (b.value - a.value) || (a.type - b.type);    
});

console.log(tips); // 4=>10​, 2=>4, 3=>4, 1=>3​​​​​​​​​​​​​​​​​
