7.  def onBeforeExit(listener: (ExitCode) => Any): Process

   This event is emitted when Node.js empties its event loop and has nothing else to schedule.

   This event is emitted when Node.js empties its event loop and has nothing else to schedule. Normally, Node.js exits when there is no work scheduled, but a listener for 'beforeExit' can make asynchronous calls, and cause Node.js to continue.

   'beforeExit' is not emitted for conditions causing explicit termination, such as process.exit() or uncaught exceptions, and should not be used as an alternative to the 'exit' event unless the intention is to schedule more work.

   If process is spawned with an IPC channel, 'disconnect' will be emitted when IPC channel is closed.

9.  def onExit(listener: (ExitCode) => Any): Process

   Emitted when the process is about to exit.

   Emitted when the process is about to exit. There is no way to prevent the exiting of the event loop at this point, and once all 'exit' listeners have finished running the process will exit. Therefore you must only perform synchronous operations in this handler. This is a good hook to perform checks on the module's state (like for unit tests). The callback takes one argument, the code the process is exiting with.

22.  def onUncaughtException(listener: (Error) => Any): Process

    The 'uncaughtException' event is emitted when an exception bubbles all the way back to the event loop.

    The 'uncaughtException' event is emitted when an exception bubbles all the way back to the event loop. By default, Node.js handles such exceptions by printing the stack trace to stderr and exiting. Adding a handler for the 'uncaughtException' event overrides this default behavior.

23.  def onUnhandledRejection[T](listener: (Any, Promise[T]) => Any): Process

    Emitted whenever a Promise is rejected and no error handler is attached to the promise within a turn of the event loop.

    Emitted whenever a Promise is rejected and no error handler is attached to the promise within a turn of the event loop. When programming with promises exceptions are encapsulated as rejected promises. Such promises can be caught and handled using promise.catch() and rejections are propagated through a promise chain. This event is useful for detecting and keeping track of promises that were rejected whose rejections were not handled yet.

24.  def onWarning(listener: (Warning) => Any): Process

    A process warning is similar to an error in that it describes exceptional conditions that are being brought to the user's attention.

    A process warning is similar to an error in that it describes exceptional conditions that are being brought to the user's attention. However, warnings are not part of the normal Node.js and JavaScript error handling flow. Node.js can emit warnings whenever it detects bad coding practices that could lead to sub-optimal application performance, bugs or security vulnerabilities.

    The event handler for 'warning' events is called with a single warning argument whose value is an Error object.
