What is Joi
Joi is a powerful schema validation library for JavaScript applications. It provides a simple and expressive API for defining schemas and validating data against those schemas. Originally developed as part of the hapi.js framework, Joi has since been extracted into a standalone package and can be used in any JavaScript environment, including Node.js and browser-based applications.
