Answer 1

details[0]将返回数组中的第一个对象

  

{name：“Shiva”，名称：“SE”，地址：{...}}

details[0]['name']将返回第一个对象的属性名称

  

“希瓦”

这应该给你一个很好的起点：

var str = ''; 
details.forEach(person => {
     var address = person.address;   
     var mobiles = address.mobileno;
     str += `Name ${person.name}\nDesignation: ${person.designation}\nPhone: ${mobiles.join(' ')}\nStreet No: ${address.streetno}\n\n`; 
})

console.log(str)

让代码尽可能可读是非常重要的，所以尽量保持整洁：）

总是想到下一个会出现并编写代码的程序员。
