Today was the final Web Dev cohort session.

The best part wasn't the code.

It was seeing people show up every single day, stay consistent, help each other, and keep building.

Today's session with @Hiteshdotcom & @piyushgarg_dev Sir wasn't about prompting models.

It was about building reliable AI systems around them.

⚛️ 𝗙𝗼𝗿𝗺 𝗵𝗮𝗻𝗱𝗹𝗶𝗻𝗴

Today’s class with @Hiteshdotcom & @piyushgarg_dev Sir went deeper into handling forms and structuring apps properly.

Also saw how small decisions in structure make code easier to scale later
