我想在嵌套的对象数组中找到一个数组,我该怎么做?这是我的数组const arr = [ { "teamA": [ { "_id": "5fcb57c5a1a426c03bcfd25f", "level": 10, "username": "asaf" } ], "teamB": [], "options": {} }, { "teamA": [ { "_id": "a7fgy3h1uio", "level": 10, "username": "asaf" } ], "teamB": [ { "_id": "13rfedsc32", "level": 10, "username": "asaf" }, { "_id": "dghg453r3q", "level": 10, "username": "asaf" } ], "options": {} }];现在我想创建一个函数,通过 _id 返回玩家所在团队的数组例如,我创建了这个:const findTeam = playerId => { const match = arr.find(({ teamA, teamB }) => [teamA, teamB].some(team => team.some(i => i._id == playerId))); if(!match) return; const { teamA, teamB } = match; const team = [teamA, teamB].find(team => team.some(i => i._id == playerId)); return team;};它正在工作,但是我这样做的方式看起来很混乱,有什么巧妙的方法可以做到这一点吗?谢谢!

您可以使用flatMap
:
const arr = [{teamA:[{_id:"5fcb57c5a1a426c03bcfd25f",level:10,username:"asaf"}],teamB:[],options:{}},{teamA:[{_id:"a7fgy3h1uio",level:10,username:"asaf"}],teamB:[{_id:"13rfedsc32",level:10,username:"asaf"},{_id:"dghg453r3q",level:10,username:"asaf"}],options:{}}];
const findTeam = playerId => arr.flatMap(({ teamA, teamB }) => [teamA, teamB])
.find(team => team.some(player => player._id === playerId));
console.log(findTeam('13rfedsc32'));
