Override Inherited Methods Question

I continually get an error on my local PC when attempting to update the prototype explicitly. However, the same language passes the FCC test for “OOP: Override Inherited Methods”.
Javascript seems very happy to do the prototype work implicitly when the prototype keyword is removed, as below:

class User {
    constructor(userName, password) {
        this.userName = userName;
        this.password = password;
    speak() {
        return "Hello there!"

var user1 = Object.create(User.prototype);

var myUser = Object.create(User.prototype);
myUser.userName = "kevin";
myUser.password = "password";

// no prototype required here
myUser.speak = function() {
    return "talking...";


Am I doing something wrong, or is this simply ES6 syntactic sugar?

I’m not exactly sure what you’re asking. You aren’t updating the prototype here. The prototype is unchanged. You are updating the speak() function for a single instance of a User object.
