I keep getting error in console:
app.js:23 Uncaught ReferenceError: message is not defined
at new ChatMessage (app.js:23)
at app.js:8
in apo.js:
class ChatApp {
constructor(){
socket.init(‘ws://localhost:8000’);
socket.registerOpenHandler(() => {
let message = new ChatMessage({ message: ‘Hello’ });
socket.sendMessage(message.serialize());
});
socket.registerMessageHandler((data) => {
console.log(data);
});
}
}
class ChatMessage {
constructor({
message: m,
user: u=‘Nader’,
timestamp: t=(new Date()).getTime()
}) {
this.message = message;
this.user = user;
this.timestamp = timestamp;
console.log(message);
}
serialize(){
return {
message: this.message,
user: this.user,
timestamp: this.timestamp
};
}
}
