If you have ever worked with forms on a website (e.g. registration, login, order, personal information update, etc.), you know that validation is an important part. You want to make sure that the data users enter is in the correct format, that important fields are not left blank, that the email address is valid, that the phone number is long enough, and that the password is complex enough.

There are many libraries that support form validation. One of the popular and flexible choices is Yup. Yup is a library that helps you define a schema for data validation in a simple, readable, and benin phone number material powerful way.
