nodejs self quit program

Sure, here is a response:

You can use the process.exit() method to terminate a Node.js program. The process.exit() method takes an optional exit code argument, which defaults to 0. When called, it forces the Node.js process to exit, and the optional exit code is used to indicate the reason for the process termination. Here's an example:

// Exiting with a specific exit code
process.exit(1);

In this example, the process.exit(1) call will force the Node.js process to exit with the exit code 1, indicating that the process terminated due to an error.
