       for(b in quizs[i].quests[j].reps){
           //quizs[i].quests[j]["quizId"]
        /*   if(quizs[i].quests[j].reps[b]["stat"]==null){
               var l = 1;
           }
           else{
               var l =quizs[i].quests[j].reps[b]["stat"]

You can't use for in array declaration.

var PieData = [];
for (var b in quizs[i].quests[j].reps) {
    PieData.push({
        value: 2,
        startAngle: 240,
        color: "{{h}}",
        label: quizs[i].quests[j].reps[b]["rep"]
    });
}

Array#map will looks cleaner here

var PieData = quizs[i].quests[j].reps.map(i => ({
    value: 2,
    startAngle: 240,
    color: "{{h}}",
    label: i.rep
}));
