First, listen to the middle part and leave a comment. Job seekers who want to get a job in the front-end, please listen. The reason is that 1. It doesn't spoon-feed This lecture is very good, and if you ask a great instructor about something you don't know, he will explain it in a summary and show you a screen for 5 minutes => If you go back to your seat, Google what you just saw, and look up more docs, it's a lecture that you can understand what he showed you. But it's not to the extent that you can't really follow. If you don't understand it like me, you can skip over it and just watch the lecture, unless you have a rough personality that always skips over it. I added one OOP design pattern that comes up in the beginning, read the firebase docs, and read chakra. You have to study by yourself to see the big picture and study to get a job. 2. Unknown library Chakra I tried Chakra for the first time. He didn't explain in detail how to use it and just showed it to me. However, if you feel like you're working at a company, find the docs on your own, get used to it a little, and follow along, it's fine. In fact, it is not a front-end lecture to explain styling libraries in detail. 3. Refactoring While following the lecture, if you write some code and it becomes complicated or you feel the need for reuse, it is good to move the code and rewrite it. 4. Coupon Shingong The instructor also posts on Medium, and if you look for the article there, it seems to be no secret that there are coupons with high discount rates. 5. Highly recommended It may be because I am a beginner, but there is not a single thing that can be glossed over in the lecture, and it seems that a lot of thought was put into the editing and composition. Also, the 3-month course period seems long, but it is also a bit stressful, so even when I am playing around, I come back thinking, "Oh, I have to take the lecture." I think this is the perfect lecture for Deadline Driven Development. 6. Q&A I have been asking a lot of questions, but you explain them well. Thank you for uploading a great lecture!
