How to get values ​​from objects?

Question

JavaScript

There is a JSON like:

[
 {
  "name": "Anton",
  "lastname": "Romanov"
   "rank": "admin"
 },
 {
  "name" "Andrey",
  "lastname": "Ivanov"
  "rank":  "admin"
 },
 {
  "name": "Vasya",
  "lastname": "Antonov"
   "rank": "admin"
 },
 {
  "name" "Ivan",
  "lastname": "Andreev"
  "rank":  "admin"
 }
 {
  "name" "Ivan",
  "lastname": "Vasiliv"
  "rank":  "player"
 }
]

How can I get information about all values ​​of rank: admin, and use, for example:
console.log(`Admins: ${admins}`) - lists name and lastname of all admins separated by commas.

Answer 1

const users = [ .......  ]
const admins = users.filter(user => user.rank === 'admin').map(user => `${user.lastname} ${user.name}`).join(', ');
console.log(`Админы: ${admins}`);

Answer 2

JSON.parse() , Array.filter() , Array.map() , Array.join()

Answer 3

const admins = data
  .filter(n => n.rank === 'admin')
  .reduce((acc, n) => {
    acc += `${n.name} ${n.lastname}, `;
    return acc;
  }, '').trim().replace(/,$/, '.');
