Sorting an array of objects by a property

I have an array that looks like this:

var people = [
  {name: "John", age:15},
  {name: "Betty", age:12},
  {name: "Zach", age:22}
];

And I need to sort it by name, here's how to do it:

people = people.sort(function(a, b){

  var aName = a.name.toLowerCase();
  var bName = b.name.toLowerCase();

  if(aName > bName) return 1;

  if(aName < bName) return -1;

  return 0;

});
