## 5 . Group ou Aggregate contando a quantidade de pokemons de cada tipo
```js
> db.pokemons.group({
... initial: {total: 0},
... reduce: function(current, result){
... result.total++;
... current.types.forEach(function(type){
... if(result[type]){
... result[type]++;
... } else {
... result[type] = 1;
... }
... });
... }
... });
[
{
"total" : 610,
"fire" : 47,
"water" : 105,
"normal" : 78,
"flying" : 77,
"bug" : 61,
"poison" : 54,
"steel" : 37,
"electric" : 40,
"ice" : 24,
"ghost" : 34,
"fighting" : 38,
"psychic" : 62,
"grass" : 75,
"ground" : 51,
"fairy" : 28,
"rock" : 46,
"dark" : 38,
"dragon" : 20
}
]
```

## 6. Realizar 3 counts na pokemons.

-> .count -- todos
-> .count -- só tipo fogo
-> .count -- só de quantos tem a defesa maior que 70

```js
// .count -- todos
> db.pokemons.count()
610


// .count -- só tipo fogo
> db.pokemons.count({types: "fire"})
47

// .count -- só de quantos tem a defesa maior que 70
> db.pokemons.count({defense: {$gt: 70}})
250

```
