How to push an object into an array?

Question

JavaScript

Wrote such a piece of code, but something is not right.

let users = [];
...
users[socket] = {}; // Создаем новый объект
users[socket].id = results[0].id; // ID пользователя из бд
users[socket].nickname = results[0].nickname;
users.push(users[socket]); // Пушим, надо сохранить сокет как ключ, ибо по нему идёт перебор пользователей
...

How to properly push an object into an array?

Answer 1

const users = [];
// ...
const server = net.createServer((socket) => {
    const newUser = {};
    newUser.socket = socket;
    newUser.id = results[0].id; // ID пользователя из бд -- не знаю уж где вы его возьмете
    newUser.nickname = results[0].nickname;
    users.push(newUser);
    c.on('data', function(data) {
});

And for some reason, you first declare an array, then you write down the ID in its properties. There will be no error, but it will no longer be an array.
Moreover, you specify a reference to an object as the property name, this is not WeakMap.

Answer 2

An array is not an object. An object can be cast into an array, not vice versa.
