Sort function doesn't work properly for array size >10 in chrome

ditchysort.js

function Person(name,city){
    this.name=name;
}
var sorted=[];
var sortDitchedMe=[];
for(var i=1;i<=11;i++){
    var person=new Person('name'+i);
    if(i<11){
        sorted.push(person);
    }
    sortDitchedMe.push(person);
}
function sorter(a,b){
return 0;
}
console.log(sorted.sort(sorter));
//[{name:'name1'},{name:'name2'}.....,{name:'name10'}]
console.log(sortDitchedMe.sort(sorter));
//[{name:'name6'},{name:'name1'},{name:'name3'},{name:'name4'},{name:'name5'},{name:'name2'}.....,{name:'name10'},{name:'name11'}]
