在 React Native JavaScript 中使用 Arrays 中的 Arrays

Question

我從 API (JSON) 接收這種類型的數組：

 {
    "api": {
        "results": 13,
        "players": [
            {
                "player_id": 79308,
                "player_name": "Felipe Ponce Ramírez",
                "firstname": "Felipe",
                "lastname": "Ponce Ramírez",
                "number": null,
                "position": "Midfielder",
                "age": 32,
                "birth_date": "29/03/1988",
                "birth_place": "Ciudad Lerdo",
                "birth_country": "Mexico",
                "nationality": "Mexico",
                "height": "177 cm",
                "weight": "67 kg",
                "injured": null,
                "rating": null,
                "team_id": 4299,
                "team_name": "Alianza",
                "league_id": 2979,
                "league": "Primera Division",
                "season": "2020-2021",
                "captain": 0,
                "shots": {
                    "total": 0,
                    "on": 0
                },
                "goals": {
                    "total": 5,
                    "conceded": 0,
                    "assists": 0,
                    "saves": 0
                },
                "passes": {
                    "total": 0,
                    "key": 0,
                    "accuracy": 0
                },
                "tackles": {
                    "total": 0,
                    "blocks": 0,
                    "interceptions": 0
                },
                "duels": {
                    "total": 0,
                    "won": 0
                },
                "dribbles": {
                    "attempts": 0,
                    "success": 0
                },
                "fouls": {
                    "drawn": 0,
                    "committed": 0
                },
                "cards": {
                    "yellow": 2,
                    "yellowred": 0,
                    "red": 0
                },
                "penalty": {
                    "won": 0,
                    "commited": 0,
                    "success": 0,
                    "missed": 0,
                    "saved": 0
                },
                "games": {
                    "appearences": 7,
                    "minutes_played": 260,
                    "lineups": 3
                },
                "substitutes": {
                    "in": 4,
                    "out": 3,
                    "bench": 0
                }
            }
    // From here on there are 4 objects like this (there are 1 object for the last 5 seasons
           }
        ]
    }
}

所以我想將對象提取到 3 Arrays 中：

"goals": {
                    "total": 5,
                    "conceded": 0,
                    "assists": 0,
                    "saves": 0
                },
"cards": {
                    "yellow": 2,
                    "yellowred": 0,
                    "red": 0
                },
"games": {
                    "appearences": 7,
                    "minutes_played": 260,
                    "lineups": 3
                },

我有這個代碼來接收我的動作文件中的數據（它提供給我的減速器）：

你的意思是這樣嗎？

result =  [
  {
    "total": 5,
    "conceded": 0,
    "assists": 0,
    "saves": 0
