21 Advanced Claude Prompts for Coding

I remember one night, my code not running and my tea also getting cold. I was staring at screen like it is staring back at me. That time I found claude prompts for coding and honestly, it felt like someone sit beside me and helping. I started using very simple prompts and Claude was giving full code, clean steps, and even fixing my silly mistakes. I was feeling less scared of coding after that. My mind was more calm. My laptop also looked happier, I think.

Now I also use AI coding assistant prompts, debugging prompts, and code optimization prompts when my project feel heavy and messy. Claude explain things slowly and nicely. It does not make me feel dumb. I learn small small things every day. And that feels good. Very good. Even my friends now ask me, “Bro how you coding so fast?” I just smile and sip my tea again.
