Good lecture, I'll go after listening to it. ㅎㅎ Even though it wasn't my first time using TypeScript, I learned about parts that I had overlooked and various tips (+ concepts). Thank you for the detailed explanation. ps. I thought that it would be more fun for beginners if there were mini-projects that actually worked in the basic lecture. :) If you have time in the future, please refer to it. ㅎㅎ Thank you.
