How can I call the method?

Question

Can someone help me with that calling issue, please? Not sure how can I call a method not a class.
```User.js
class User {
    constructor(email, username, birthday) {
        this.email = email;
        this.username = username;
        this.birthday = birthday;
    }
changeUsername(username) {
    this.username = username;
}
}
var user1 = new User('JavaScriptStudent@teamtreehouse.com', 'JSUser1', '1/08/1991');
```

You call your method from the class instance with dot notation. 
Try the following:
```javascript
class User {
    constructor(email, username, birthday) {
        this.email = email;
        this.username = username;
        this.birthday = birthday;
    }
changeUsername(username) {
    this.username = username;
}
}
const user1 = new User('JavaScriptStudent@teamtreehouse.com', 'JSUser1', '1/08/1991');
console.log(user1.birthday);
console.log("username before method call --> " + user1.username);
user1.changeUsername('did this work?');   // this is the method call
console.log("username after method call --> " + user1.username);
// output:
1/08/1991
username before method call --> JSUser1
username after method call --> did this work?
```
