Validation Without Rage Clicks

Hey Demo,

Nothing derails a form faster than confusing validation. A user fills everything out, clicks submit ... and nothing happens. Or worse, they get a vague error like "Something went wrong" with no clue what field needs attention. That's how you get rage-clicks, frustrated reloads, and abandoned forms.

Better validation keeps forms moving.

• Debounce your real-time checks so inputs don't flash errors on every keystroke.
• Hold back error messages until blur, and always place them where people expect to find them — same tone, same spot, every time.
• And don't stop at the client. Always round-trip to the server. That's where the real rules live, and the only way to catch edge cases and spoofed inputs.

One simple improvement: show example formats below tricky fields like email or phone numbers. It prevents guesswork and reduces failed submissions.
