16. function(doc) {

for(var i = 0 ; i < doc.data.length ; i++ ) {
if(doc.data[i].player && doc.data[i].score){
emit({player:doc.data[i].player,name:doc.data[i].name}, doc.data[i].score);
}
}
}
}
列舉data並以
({player: player_id, name: player_name}: score)
建立View
Source:
一筆scores資料
Result:
一筆view資料

17. function(key, values, rereduce){
return sum(values);
}
將原資料型態({player: player_id, name:
player_name}: score)其中的Score以作分
組(group by key)加總
Source:
以{user資訊: 答對題目數}
為資料型態的資料
Result:
以user資訊為群組，加總答對題目
數，建立相同資料型態的資料
