How does yargs.port work?

yargs.port is an API in the Yargs library for defining a command-line option for a port number, allowing users to specify a port number as an input to the command-line interface. When using the yargs.port method, the argument for the option can be a boolean or a string, and Yargs will automatically parse the user input as a port number.

const argv = require("yargs").number("port").argv;

console.log(argv.port);

This will allow you to pass a port number to your script as an argument, like --port 8080. The value of argv.port will be a number, or NaN if no port number was provided.
