I was interested in full stack, so I decided to try TypeScript since I was going to do it anyway, so I took the course. There were many similar usages to Java, so it wasn't too difficult to understand, and I think even people with no basic knowledge will be able to understand it without difficulty. While taking the course, I looked back at the JS grammar I used before, compared it to TS, and studied the differences separately. I will use what I learned so that I can use it well in React and NextJS later! I enjoyed the course :D
