About This Episode:

Your form validation just got smarter 💪

We’ve built forms, validated input, and handled errors… but what if we could preserve user data, show field-specific messages, and make validation feel seamless? ⚡️

👉 In this episode, you’ll learn how to:

🧠 Use sessions to persist form data across redirects
💬 Display inline validation errors with EJS helpers
⚙️ Implement a back() method for clean redirects
✨ Create a smoother, stateful user experience — no frameworks required

By the end, your Node.js app will remember what users entered, show precise errors, and feel more interactive 🔥
