(Edit) I left a review before without properly attending the lecture. As expected, Mr. Zerocho is a true gentleman. In my case, I went through it without knowing anything about TypeScript, but he explained TypeScript in detail and there was even a manual on GitHub, so it was easy. Those who are using m1, don't worry. The instructor has a guide on how to install m1 on GitHub, so you can try it. Thanks to him, I was able to apply it right away in my field. Thank you.
