Events

Node.js supports concurrency by using events and async function calls. Events are actions that trigger other actions. We can use Event.fire(name, [data]) to fire an event with optional data and Event.on(name, callback) to bind one or more listeners to an event.

For a comprehensive list of the available methods, refer to the official documentation.

Sending an email

Suppose that we want to fire an event every time a user visits the /send_email_with_events route and send an email inside the event listener.
