Script Preparation code:

var objs = []
var i = 0
for (i; i < 100000; i++) {
  var obj = {}
  obj.x = Math.random() * 100
  obj.y = Math.random() * 100
  obj.z = Math.random() * 100
  objs.push(obj)
}

Tests:

IF statement
objs.sort((a, b) => { if (a.x != b.x) { return a.x - b.x } if (a.y != b.y) { return a.y - b.y } return a.z - b.z })
OR assignment
objs.sort((a, b) => { return (a.x - b.x) || (a.y - b.y) || (a.z - b.z) })
