One of the most common uses of client-side JavaScript is to validate form data. When we say “validate” form data, we mean ensuring that the data entered is clean, error free, formatted correctly, and meets certain criterion. The validation of input data is crucial because it ensures that the data is captured in a format that can be used most efficiently. Web designers and developers use client-side JavaScript as one method for validating user-inputted data. The purpose of this project is to build an HTML5 registration form and use JavaScript functions to validate user-inputted data.
