In Java, any method can call System.exit(int status), unless a security manager does not permit it. This will terminate the currently running Java Virtual Machine. "The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination." [8]

The code associated with a graceful exit may also take additional steps, such as closing files, to ensure that the program leaves data in a consistent, recoverable state. Graceful exits are not always desired.
] Node.js's event loop does not need to be called explicitly. Instead, callbacks are defined, and the server automatically enters the event loop at the end of the callback definition. Node.js exits the event loop when there are no further callbacks to be performed.
Plug'n'Play allows users to run Node projects without node_modules folder, defining the way or location to resolve dependencies package files with the Plug-n-Play-control file. This feature is aimed to fix an unwell structured node_modules architecture and resulting in a faster Node.js application start-up time.

Most modern code editors and IDEs allow you to set up a localhost server – eg. use atom-live-server in Atom, and Live Server in VS Code. WebStorm and PhpStorm have the feature built in, without requiring an extension. You can also use a third party program such as Node.js's npx http-server command (video tutorial), or XAMPP.
