为什么我不能从我的数组中抓取特定的对象？

Question

for (var statementCounter = 0; statementCounter < 23; statementCounter++) {
  secularScores.push([scores[statementCounter][0], scores[statementCounter][1]]);
  if (sorted == false) {
    secularScores.sort(function (a, b) {
      return b[1] - a[1]
    });
    sorted = true;
  } else {
    console.log(secularScores); // this works
    console.log(secularScores[0]); // this works
    console.log(scores[statementCounter]); // this works
    console.log(scores[statementCounter][0]); // this works
    console.log(secularScores[statementCounter]); // this doesn't work
    console.log(secularScores[statementCounter][0]); // this doesn't work"Uncaught typeError: Cannot read property of '0' of undefined"
  }
}

我不明白的是为什么底部的不起作用。

我推入 secularScores 的数组工作得很好，我可以从中获取任何特定对象，但是当我尝试从 secularScores 中获取特定对象时，它说它未定义。

secularScores[statementCounter] says undefined.
secularScores[statementCounter][0] says Error: cannot read property '0'of undefined.

这是数组（console.log(secularScores) 的结果）

我发现我的排序功能弄乱了我的结果，导致了这个问题。 谢谢大家，为我提供帮助。
