Hello dualsrn1230, Thank you so much! 😊 My goal for this lecture was to help you build a solid foundation from the ground up so that you can continue to use it in practice, and I am truly happy that you felt that way. As you mentioned, Claude Code is not a tool you just learn once and forget; it’s a tool where your understanding deepens and your productivity increases significantly the more you use it, so repetitive learning is very important. If you continue to use it in your actual work and build a sense of "Ah, this is how I use it in this situation," you will grow much faster. Thank you once again for the great feedback! 🚀
