Javascript-根据存在于单独数组中的键的值过滤对象数组

当我在开发第一个应用程序时，这对Javascript来说还很陌生，我从R过来了，尽管数据操作（使用dplyr甚至是基本R）变得非常容易，但是我目前正在为此而苦苦挣扎。我有以下数据：

var teamsA = ['team1', 'team2', 'team3'];
var teamsB = ['team4', 'team5', 'team6'];

var teamgroup = A;

var myData = [
    {player: "Joe", team: "team1"},
    {player: "Tom", team: "team3"},
    {player: "Red", team: "team2"},
    {player: "Smi", team: "team5"},
    {player: "Bib", team: "team6"},
    {player: "Cat", team: "team2"},
    {player: "Dan", team: "team3"},
    {player: "Jim", team: "team1"}
]

使用显示的数据，问题非常简单：我想根据teamgroup变量确定的数组中存在的团队过滤myData 。即：

if(teamgroup == "A") { 
    myData.filter(team in teamsA) 
} else {
    myData.filter(team in teamsB)
}

...不太清楚如何使用javascript。最好使用新的ES6东西。谢谢！
