Thank you, teacher. In the first class of the basic course, you said that JavaScript is the point of contact with the user, which touched my heart. I wanted to become a developer who thinks of the customer first, and I think I feel more proud as a front-end developer. I learned so much through the basic and intermediate-advanced courses!! It was amazing how things that I had found difficult when I tried to approach them in terms came to be understood naturally when I understood how the JavaScript engine works. This was exactly the lecture I wanted, and now I'm going to finish the ES6 basic and advanced courses. ㅎㅎ I want to apply it well in React and in real life, but I'm not sure exactly, but I'll try to do it well. ㅎㅎ Thank you so much for recording such a great lecture!
