javascript - 如何在 javascript 中实现有偏差的平均年龄？

Question

如何在 javascript 中实现带有偏差的平均年龄？ 我需要制作一个 Javascript 算法:

• 询问10个人的姓名和年龄；
• 打印人的“平均年龄”屏幕；
• 打印每个人的姓名和年龄与平均值的偏差。

我试着一个一个地写每个提示，但想知道是否有办法缩短这段代码

var input = prompt('Enter your name');
var name1 = input;
input = prompt('Enter your age:');
var age1 = parseInt (input);

var input = prompt('Enter your name');
var name2 = input;
input = prompt('Enter your age:');
var age2 = parseInt (input);

[...]

var input = prompt('Enter your name');
var name10 = input;
input = prompt('Enter your age:');
var age10 = parseInt (input);

var average = (age1+age2+age3+age4+age5+age6+age7+age8+age9+age10/10);

console.log(`Average age: ${average}`);
console.log(`Name: ${name1}, Age: ${age1}, Deviance: ${deviance1}`);
console.log(`Name: ${name2}, Age: ${age2}, Deviance: ${deviance2}`);
[...]
console.log(`Name: ${name10}, Age: ${age10}, Deviance: ${deviance10}`);

我不知道如何做偏差(分析值与平均值的差异)

下面的另一个解决方案。我在代码中添加了一些注释以提供帮助。 如果您有任何问题，请告诉我:)

const MAX_NAMES = 3;

// Each person will be stored in this array below
let people = [];
// Store the total combined age in totalAge variable
let totalAge = 0;

for(let i = 0; i < MAX_NAMES; i++) {
    let nameValue = prompt('Enter your name');
    let ageValue = parseInt(prompt('Enter your age'));
    // Add to the total age
    totalAge += ageValue;
    // we add an object to the array. 'name' and 'age' are the object Keys. We reference the keys to get the values back from the object later
    people.push({ name: nameValue, age: ageValue })
}

// Print the Average Age of People
let averageAge = Math.round(totalAge / people.length);
console.log(`The average age is ${averageAge}`);

//Print each person's name and deviation from age to average.
for(let person in people) {
    console.log(`Name: ${people[person].name} Deviation: ${Math.abs(people[person].age - averageAge)}`);
}
