Answer 1

I had an array of strings, not objects and i used this approach:

ng-repeat="name in names | unique"

with this filter:

angular.module('app').filter('unique', unique);
function unique(){
return function(arry){
        Array.prototype.getUnique = function(){
        var u = {}, a = [];
        for(var i = 0, l = this.length; i < l; ++i){
           if(u.hasOwnProperty(this[i])) {
              continue;
           }
           a.push(this[i]);
           u[this[i]] = 1;
        }
        return a;
    };
    if(arry === undefined || arry.length === 0){
          return '';
    }
    else {
         return arry.getUnique(); 
    }

  };
}
