Answer 1

for (let i = newUsers.length; i < 7; i += 1) {
 newUsers.push({ _id: i + 1, users: 0 });
}

Answer 2

According to this W3Schools article, you can use map operator to change all the users property.

const newUsers = [
 {
 _id: 1,
 users: 8
 },
 {
 _id: 2,
 users: 6
 },
 {
 _id: 3,
 users: 1
 },
 {
 _id: 4,
 users: 8
 },
 {
 _id: 5,
 users: 8
 }
]
if (newUsers.length < 7) 
 newUsers.map(x => x.users = 0);
 
console.log(newUsers)
