callback
error
connect
reconnect
Answer is Right!
Answer is Wrong!
The correct answer is: A. callback
A callback function is a function that is called when a certain event occurs. In the context of the question, the callback function is called when an error event occurs.
The other options are incorrect because:
- B. error is not a function. It is a keyword that is used to specify that an error has occurred.
- C. connect is a function that is used to connect to a server.
- D. reconnect is a function that is used to reconnect to a server after a connection has been lost.
