How to store an objects in array after method in my class

Question

Please see my code below.

class User {
  
  constructor(name, email) {
    this.name = name;
    this.email = email;
   
  }
  
  addUser() {
    users.push(this.name, this.email)
  }
  
}

const userOne = new User ('John', '[email protected]');
const userTwo = new User ("Alan", "[email protected]");

let users = [];

userOne.addUser();
userTwo.addUser();

After method addUser i have array with names and emails but i would like to have an array with objects as below

users = [
{ name: 'John', email: '[email protected]' }
{ name: 'Alan', email: '[email protected]' }
]

How my method addUser should looks in my prototype and if variable users is in correct place or can be store somewhere in Class? Thanks in advance

Thanks, but I was looking for method to my prototype as my template — deepen

It is an antipattern to have a method that mutates a global variable. It goes against the OOP principles. — trincot

You're pushing the object properties one after the other, rather than as an object together.

Try this for your addUser method:

addUser() {
  users.push({name: this.name, email: this.email})
}

You just need to push each proprieties

users.push({name: this.name, email: this.email})

If you want to do this automatically you can use:

users.push(Object.assign({}, this))

Or you cloud just pass the whole object:

users.push(this)

Anyhow, I would suggest not to use users globally.
