Smart Forms in Next.js🧠Loading Button + Detect Updated Fields (React Hook Form Guide)

Описание: In this episode of our Next.js + MySQL Job Portal Application, we will make the employer profile form smarter and more user-friendly.

You will learn two powerful features of React Hook Form:
✅ isSubmitting – Show a loading animation and dynamic text on the submit button
✅ isDirty – Detect exactly when the user changes any field, perfect for pre-filled forms

We are also applying this on our Employer Profile Page, where all past data is pre-filled when the employer revisits the form — making updates faster, easier, and more accurate.
