I took this course to learn Vue3 properly after trying Vue2 at an academy. At first, I tried to learn through the official documentation. It was really hard to understand, whether it was because I was not good at English or because I lacked knowledge of development. However, this course explained difficult concepts with easy examples, so I was able to build a solid foundation. In particular, when I studied on my own, I had a hard time understanding Vue's proxy object for reactivity because I lacked JS concepts. The course explained the core with easy examples, so I was able to understand it. This course explains that A goes through some internal process to perform B function, rather than A performing B function. I recommend this course to people like me who don't know much about Vue or who still have difficulty understanding the official documentation. I hope the next course comes out soon!
