In Programs, the Nodejs exit process called in two ways

one way by calling process.exit() manually. Another way is, It calls automatically when there are no pending tasks to process by the event loop.

Nodejs contains a global process object that contains the exit() method.

Here is a syntax.

process.exit([errorcode])

code is an optional integer value, default is zero, which means success. Code=1 is a failure

For success, call process.exit(0) method. This executes normally when no asynchronous operations are pending. For failure, call process.exit(1) method.
