๐Ÿš€ New Video for ServiceNow Dev Beginners!

Just dropped a quick tutorial on JavaScript form validation using onsubmit โ€” perfect for anyone learning how to improve user experience and prevent bad data from being submitted to the server.

โœ… In this video, I walk through:

  • How the onsubmit event works in JavaScript
  • Validating user input before submission
  • Using return false to stop bad form data

Form validation is one of those simple but powerful skills that every front-end developer should master. Whether you're building a login form or a contact page, getting this right can save a lot of backend headaches.
