Template Driven Form – Touched vs Untouched in Angular | Angular tutorial in Hindi (Session-255)

In this Angular session, learn the complete difference between touched and untouched states in Template-Driven Forms — two essential form control states that help you decide when to show validation errors and how to improve user experience by avoiding early error messages.

Angular automatically marks a form control as touched when the user focuses and then leaves the input field, and keeps it untouched until the first interaction happens.

Understanding these states is crucial for designing clean, user-friendly forms.
