How does joi._flags work?

In Joi, _flags is a private property that holds the validation flags that are set on a schema. These flags are used to alter the behavior of the validation process for a particular schema.

const Joi = require("joi");

const schema = Joi.string().required().min(3);

console.log(schema._flags); // outputs { presence: 'required', min: 3 }

In this example, schema._flags will return an object that contains the flags associated with the Joi.string() schema. In this case, it will show that the presence flag is set to required and the min flag is set to 3.
