JavaScript Practice Classes in JavaScript Practicing Classes Practice Adding Methods

i'm confused again

it won't work inside or outside

User.js
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");
user1['changeUsername'](TreehouseStudent2);

it seems you just copied and paste the (“TreehouseStudent2”) so i guess there is some problem with the quotation marks

This indeed seems to be the problem, after testing it in the node REPL.

It should also be noted, for future reference, that it's best to call class functions with dot notation like this:

user1.changeUsername("TreehouseStudent2");

The way here works, too, but brackets are usually reserved to call properties of the class like username etc. for readability purposes.

yes I finally did that because that's what it said is the correct response. it still won't accept it. it makes no sense

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"); user1['changeUsername']('TreehouseStudent2');

i've selected a best answer but it's not taking it.
