It was a really great lecture!! It was so much fun that I finished it in just two days 😊😊 I had done some coding before taking the lecture, so I didn't have much trouble understanding it!! I regret studying so stiffly until now 😭 I can't believe I could study so much fun 😭😭 Thank you for the great lecture and I will learn the fun technology of crawling and code it with fun! Thank you 😊😊
