Question

I have a collection objects in an array,

[{A:2, B:2},{A:2, B:3},{A:1, B: 2}, {A:1, B:1}]

I would like to have a sort result of property A then property B. Therefore, as a result it should be:

[{A:1, B:1}, {A:1, B:2}, {A:2, B:2}, {A:2, B:3}]

Answer 1

Sort by A then by B. This sort works, because if A == A then A - A is 0. And 0 || anything is always anything. So it compares A then differs to B is A's are equal.

var list = [{A:2, B:2},{A:2, B:3},{A:1, B: 2}, {A:1, B:1}];
list.sort(function (a, b) {
  return a.A - b.A || a.B - b.B
})

Using fully cross browser sort and the benefits of lazy evaluation
