I am a UIUX planner. If you are someone who can use Figma fundamentally, this lecture will help you build a deep foundation. I think the lecture structure is contained in the lecture title. I felt that the point of this lecture is to repeatedly build patterns that utilize variable in large and small ranges of the system. Even if you miss a part, I recommend that you do not skip it and practice it repeatedly just like the video. I followed the same practice even if I didn't understand it. If the results were different from the instructor's, I would replay the video. At first, my fingers understood first and then my head understood it. The instructor explains even small details in detail. Even I, who does not know much about design systems, felt that way. He also explains causes and solutions accurately and easily. It is not easy at first, but as time goes by, you get used to it and I feel proud to see the practice time shorten compared to the video time. Thank you.
