将嵌套对象值替换为具有不同结构的单独对象

Question

我有一个 NBA 球队名称的对象，结构如下：

const HomeAndAwayTeams =
{
  teams: {
    '0': { hTeam: 'San Antonio', AwTeam: 'New Orleans' },
    '2': { hTeam: 'Sacramento', AwTeam: 'Orlando' 
},
    '4': { hTeam: 'Indiana', AwTeam: 'Toronto' }, 
    '6': { hTeam: 'Chicago', AwTeam: 'Cleveland' },
    '8': { hTeam: 'Brooklyn', AwTeam: 'Miami' },  
    '10': { hTeam: 'Milwaukee', AwTeam: 'Memphis' 
},
    '12': { hTeam: 'Oklahoma City', AwTeam: 'Denver' },
    '14': { hTeam: 'Houston', AwTeam: 'Portland' }  }
}

我希望用各自的团队昵称替换城市名称。

我有一个对象设置，将昵称作为值，将城市名称作为键。

              const NBATeamsNickNames = {
                  "Atlanta": "Hawks",
                  "Boston": "Celtics",
                  "Brooklyn": "Nets",
                  "Charlotte": "Hornets",
                  "Chicago": "Bulls",
                  "Cleveland": "Cavaliers",
                  "Dallas": "Mavericks",
                  "Denver": "Nuggets",
                  "Detroit": "Pistons",
                  "Golden State": "Warriors",
                  "Houston": "Rockets",
                  "Indiana": "Pacers",
                  "LA": "Clippers",
                  "Los Angeles": "Lakers",
                  "Memphis": "Grizzlies",
                  "Miami": "Heat",
                  "Milwaukee": "Bucks",
                  "Minnesota": "Timberwolves",
                  "New Orleans": "Pelicans",
                  "New York": "Knicks",
                  "Oklahoma City": "Thunder",
                  "Orlando": "Magic",
                  "Philadelphia": "76ers",
                  "Phoenix": "Suns",
                  "Portland": "Trailblazers",
                  "Sacramento": "Kings",
                  "San Antonio": "Spurs",
                  "Toronto": "Raptors",
                  "Utah": "Jazz",
                  "Washington": "Wizards"                     
              }

我已经尝试了多种方法来替换这些值，但是如果它是嵌套的，我不知道如何访问它。

例如，我试过这样的事情：

for (const key in NBATeamsNickNames) if (key in HomeAndAwayTeams) HomeAndAwayTeams = NBATeamsNickNames[key];

这当然只有在 HomeAndAwayTeams 中的对象值未嵌套且处于基本级别时才有效。

我尝试过一些其他方法，例如 for 循环和映射，但我在迭代对象方面缺乏经验，尤其是在这种格式下，我正在尝试理解概念以这种方式访问数据并在这种情况下替换它。

HomeAndAwayTeams 的队伍数量每天都会变化，不会是一个固定的数量。当然，对象内的队伍也会每天更换。

感谢任何帮助，谢谢。

我猜你不需要迭代 HomeAndAwayTeams 对象，你需要迭代 HomeAndAwayTeams.teams。您可以使用 Object.keys 方法来完成。

这将改变您的对象。

const { teams } = HomeAndAwayTeams
      
for (const key of Object.keys(teams)) {
  if (teams[key].hTeam in NBATeamsNickNames) {
    teams[key].hTeam = NBATeamsNickNames[teams[key].hTeam]
  }
  
  if (teams[key].AwTeam in NBATeamsNickNames) {
    teams[key].AwTeam = NBATeamsNickNames[teams[key].AwTeam]
  }
}

将嵌套对象值替换为具有不同结构的单独对象
