Question

(a) When handlers are registered

(b) When handlers are deregistered

(c) When handler functions are called

(d) When handlers do not have a matching catch clause

This question was addressed to me in an international level competition.

This interesting question is from Server-Side JavaScript in portion Server-Side and Client-Side Scripting of JavaScript

Answer 1

Correct option is (a) When handlers are registered

For explanation I would say: The on() method and addListener() method perform the same task of acting as an event emitter. The on() and addListener() method is used for registering handlers.
