Validation of javascript forms - name, password, password retype validation and Number Validation

It is critical to check the user-submitted form since it may include incor- rect information. As a result, validation is required to authenticate the user. Because JavaScript allows form validation on the client side, data processing is faster than server-side validation.15 JavaScript form validation is preferred by the majority of web developers. We can validate name, password, email, date, cell numbers, and other data using JavaScript.

Example of Form Validation in JavaScript In this example, we’ll validate the name and password. The name cannot be blank, and the password cannot be less than seven characters long. On form submission, we validate the form. The user will not be sent to the next page unless the values entered are correct.
