Remix - Advanced Patterns

Given this code snippet in a Remix component, what will be logged when a message is received?

const socket = new WebSocket('wss://example.com/socket');
socket.onmessage = (event) => {
  console.log('Message:', event.data);
};
socket.onopen = () => {
  socket.send('Hello server');
};

AMessage: [data sent from server]

BMessage: undefined

CMessage: Hello server

DNo message logged

Step-by-Step Solution

Solution:

Step 1: Understand onmessage handler
It logs the data received from the server, not what client sends.
Step 2: Analyze socket.send effect
Sending 'Hello server' triggers server response, which triggers onmessage with server data.
Final Answer:
Message: [data sent from server] -> Option A
Quick Check:
onmessage logs server data [OK]

Quick Trick: onmessage logs incoming server data, not sent data [OK]

Common Mistakes:

MISTAKES

Thinking onmessage logs what client sends
Expecting no message without explicit server response
Assuming event.data is undefined
