How to sort an object array by two different values

Question

I have an object array

var arr= [  {vara:4, varb:0, varc:3}    {vara:1, varb:2, varc:0}    {vara:3, varb:1, varc:5} ..... ]

At first i want to sort the array by vara so i use

arr.sort(function(a, b){return a.vara-b.vara});

If the sorted array have equal values in vara parameter, i want to do a second sorting by varb that will only resort the objects with equal vara values and not all the array.

How is this possible?

Are your values always integers?

How about something like:

arr.sort(function(a, b){
    if (a.vara === b.vara) {
        return a.varb - b.varb
    }
    return a.vara-b.vara;
});
