Detailed explanations one by one While attending the academy, I was lacking in basic concepts, and I didn't understand the explanations well, so I searched the Internet for JavaScript and studied, and I happened to listen to the Saengwhal Coding lecture..ㅜㅜ I'm so happy that I can listen to such a great lecture for free, and I'm so happy that I understand even the parts that I didn't understand at the academy! I recommend it to those who lack basic concepts and are just starting to study JavaScript! (I took Saengwhal Coding's JavaScript Basic Language? lecture first. I recommend you listen to that lecture first and then take the course!)
