在嵌套的Json对象中深入获取数据

Question

我有嵌套JSON对象形式的数据。我想抓取一些数据来创建一个表，但它深深地嵌套在数组和对象中。我的餐桌最好的办法是什么？

如果我想抓住球队的名字，华盛顿国民队和迈阿密马林鱼队，我该如何引用这些属性？我正在使用Angular 1和ng repeat来迭代。

这是一个更长的json对象的第一部分的例子：

CMTime fragmentInterval = kCMTimeInvalid;
[aMovieFileOutput setMovieFragmentInterval:fragmentInterval];
[aMovieFileOutput startRecordingToOutputFileURL:[NSURL fileURLWithPath:       [tempFileName stringByAppendingPathExtension:@"mov"]] recordingDelegate:self];

谢谢你！

使用Array map()功能：

var res = obj.sports[0].leagues[0].events[0].competitions[0].competitors.map(function(item) {
  return item.team.location+ " " +item.team.name;
});

console.log(res);

使用for in循环：

var resArray = [];
for (var i in obj.sports[0].leagues[0].events[0].competitions[0].competitors) {          
  resArray.push(obj.sports[0].leagues[0].events[0].competitions[0].competitors[i].team.location+ " " +obj.sports[0].leagues[0].events[0].competitions[0].competitors[i].team.name);
}

console.log(resArray);
