What is password validator?
Password Validators are responsible for determining whether a proposed password is acceptable for use and could include checks like ensuring it meets minimum length requirements, that it has an appropriate range of characters, or that it is not in the history.
Why is password validation important?
Password validation in JavaScript is essential since it allows the user to create a secure password and prevents password cracking. Using JavaScript, you may add interactivity to the password and thereby notify the user until it contains all of the required characters in any order.
