I was only prototyping with Figma, and then I found out about Primer and was researching usability, but there weren't many lectures. I thought I only had to learn animation, but I was told that I had to know coding, so as a developer turned designer, I wasn't happy, but it has the advantage of being able to create designs that are easy to develop. ㅎㅎ The entire table of contents is short, but I listened to it for quite a long time, stopping and re-listening repeatedly. I don't know if my company will use the tool, but if I do, I'll have to watch the lectures again to figure out what I don't know!
