尝试使用 for...in 循环并添加一个 if/else 语句并一直说我缺少一个“）”

Trying to use for...in loop and adding an if/else statement and keeps saying i am missing a ")" 

const testScores = {
  John : 99,
  Jess : 78,
  Ryan : 89,
  Tom : 62,
  Jane: 57,
  Ben: 83
};

for (person in testScores){
  
       if (testScores[person] > 90){
       console.log("Well done "+ person ". You scored " + testScores[person])
  };

       else{
       console.log(person + " scored " + testScores[person])};
}
  • 首先是打字错误，您忘记在person和". You scored "
    • 之间添加+
  • 其次你在 if 块之后使用 ;，因此，它的程序没有编译。

const testScores = {
  John: 99,
  Jess: 78,
  Ryan: 89,
  Tom: 62,
  Jane: 57,
  Ben: 83
};

for (person in testScores) {
  if (testScores[person] > 90) {
    console.log("Well done " + person + ". You scored " + testScores[person]);
  } else {
    console.log(person + " scored " + testScores[person]);
  }
}
