Question

我需要创建一个函数测试用例，它将平面类名称列表转换为以每个学生的年龄装饰的对象文字。

应为每个学生（10岁或11岁）随机生成年龄。鉴于每个学生的年龄在每次运行时是随机的，建议测试检查年龄值为10或11岁。

举个例子：

var classList = ["Joe", "Jack", "John", "Fred", "Frank", "Barry", "Larry", "Mary",
"Harry", "Farrell", "Susan", "Monica", "Keira", "Caroline", "Harriet", "Erica",
"Luann", "Cheryl", "Beth", "Rupa", "Linda", "Allison", "Nancy", "Dora"];

var classListWithAges = [{"name":"Joe","age":11},{"name":"Jack","age":10},
{"name":"John","age":11},{"name":"Fred","age":11},{"name":"Frank","age":11},
{"name":"Barry","age":11},{"name":"Larry","age":11},{"name":"Mary","age":11},
{"name":"Harry","age":11},{"name":"Farrell","age":10},{"name":"Susan","age":10},
{"name":"Monica","age":11},{"name":"Keira","age":10},{"name":"Caroline","age":10},
{"name":"Harriet","age":11},{"name":"Erica","age":11},{"name":"Luann","age":10},
{"name":"Cheryl","age":11},{"name":"Beth","age":10},{"name":"Rupa","age":11},
{"name":"Linda","age":10},{"name":"Allison","age":10},{"name":"Nancy","age":10},
{"name":"Dora","age":10}]

现在这里是首发代码：

// See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random
function getRandomIntInclusive(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

function decorateClassListWithAges(classList) {
  // your code here
}

任何帮助怎么做？我真的很困惑。

Answer 1

function decorateClassListWithAges(classList) {
    var list = [];
    classList.map(function(n){
        list.push({ name: n, age: getRandomIntInclusive(10,11) });
    });
    return list;
}

var classListWithAges = decorateClassListWithAges(classList);

Answer 2

function decorateClassListWithAges (classList) {
  return classList.map(name => {
    return {
      name: name,
      age: getRandomIntInclusive(10, 11)
    }
  })
}

const result = decorateClassListWithAges(classList)

console.log(result)

Answer 3

function decorateClassListWithAges() {
  for (let student of classList) {
    classListWithAges.push({name: student, age: getRandomIntInclusive(10, 11)});
  }
}

或

classListWithAges = classList.map(function(student) {
  return { name: student, age: getRandomIntInclusive(10, 11) };
})

JS中的测试用例函数
