在JavaScript中打印对象数组

如何打印此对象数组：

vStu1 = {id:"12345", name:"Dave Smith", testScore:10};
vStu2 = {id:"43531", name:"Emma Black", testScore:17};
vStu3 = {id:"97894", name:"Sue Davies", testScore:14};
arrStudents = [vStu1, vStu2, vStu3];

以这种格式：

ID:99999姓名：XXXXXXXXX测试分数：99

ID:99999姓名：XXXXXXXXX测试分数：99

---

ID:99999 Name:xxxxxxxxx TestScore:99

您可以使用foreach迭代数组并使用格式化字符串输出它：

arrStudents.forEach(s => console.log(`ID: ${s.id} Name: ...`));

您需要此功能：

vStu1 = {id:"12345", name:"Dave Smith", testScore:10};
vStu2 = {id:"43531", name:"Emma Black", testScore:17};
vStu3 = {id:"97894", name:"Sue Davies", testScore:14};
arrStudents = [vStu1, vStu2, vStu3];

/**
 * result variable is this string:
 * "ID: 12345 Name: Dave Smith TestScore: 10
 * ID: 43531 Name: Emma Black TestScore: 17
 * ID: 97894 Name: Sue Davies TestScore: 14"
 */
const result = arrStudents
  .map(student => `ID: ${student.id} Name: ${student.name} TestScore: ${student.testScore}`)
  .join('\n');
