I am a full-stack web developer with 9 years of experience. I bought a book to study Vue3 for this project, but the content was too hard to understand, so I took an online lecture for the first time, and I am very satisfied. I took both the basics and the practical ones, and they explained the basics step by step using examples, and then when there was a part that could be applied, they told me that I could change the basic examples like this and use it like this, so I understood it well and got a lot of practical tips. I did a lot of projects where publishing and development work were completely separated, so I actually didn't know how to use Bootstrap, but it was even better when they showed me how to use Bootstrap. I definitely recommend it to anyone who wants to study Vue3.
