[tw] eliminate dulplicates from array

[Alex Hough]

I've found a way to eliminate duplicates from an array [1] and applied it to
my code. I am not familiar enough with functions to know why it does not
work, but think that it is a simple solution.

the script is below

<script>

function eliminateDuplicates(arr) {
  var i,
      len=arr.length,
      clean=[],
      obj={};

  for (i=0;i<len;i++) {
    obj[arr[i]]=0;
  }
  for (i in obj) {
    clean.push(i);
  }
  return clean;
}

var arrToClean=[];
var out=[];
tids=['Q1','Q2','Q3','Q4','Q5','Q6'];
for (var i=0; i<tids.length; i++) {
        var t=tids[i].title;
    var score=DataTiddler.getData(tids[i],"score");
    var val=store.getValue(tids[i],"primary");
    var val1=store.getValue(tids[i],"secondary");
    var filter="[tag["+val.readBracketedList().join("]][tag[")+"]]";
    var filter1="[tag["+val1.readBracketedList().join("]][tag[")+"]]";
    var
list=store.filterTiddlers(filter).map(function(t){return"[["+t.title+"]]"});
    var
list1=store.filterTiddlers(filter1).map(function(t){return"[["+t.title+"]]"});

arrToClean.push(list.concat(list1));

}
eliminateDuplicates (arrToClean);
out.push(clean);
return out.join("\n");
</script>
