How does yargs.default work?

In yargs, the default method is used to set default values for options or arguments, which are used when those options or arguments are not provided. It takes an object as an argument, where the keys are the names of the options/arguments and the values are the default values to be used. If an option or argument is not included in the default object, it will not have a default value.

Ai Example

const argv = require("yargs").default("port", 3000).argv;

console.log(argv.port); // output: 3000

In this example, yargs.default sets the default value of the port option to 3000. If the user doesn't provide a value for the port option, the default value will be used. The argv object contains the parsed command-line arguments, and console.log(argv.port) prints the value of the port option to the console, which in this case is 3000.
