What are some examples of validation libraries?

What are some examples of validation libraries I can use in my project?

There are several popular validation libraries you can use, such as Joi, Validator.js, and Yup. Would you like to know more about any specific one?

Can you explain how to use Joi for validation?

Sure! Joi allows you to create schemas for your data. You define the structure and rules, and then validate your data against that schema. For example, you can define a schema for a user object with required fields like name and email.

What about Validator.js? How does it differ from Joi?

Validator.js is more focused on string validation and sanitization, while Joi is used for object schema validation. Validator.js provides utility functions for checking formats like email, URL, etc.

Are there any built-in validation features in frameworks like React?

Yes, React has built-in form handling capabilities, and you can use libraries like Formik or React Hook Form that integrate validation easily with Yup or other validation libraries.
