I had been using Vue2 for 19 years, but early last year, I suddenly had to switch to Vue3. I hurriedly looked for a lecture, but I couldn't find it anywhere... Then I found a Vue3 lecture on Inflearn. But it wasn't the same lecturer I had taken the Vue2 lecture with, but someone I had never met before... I was worried, but I took the Vue3 basics with my company account, and the quality was really high. So I took the Vue3 advanced course with my personal account, and I thought I had mastered it, but I heard rumors that my department was using Vueuse, nuxtjs, etc. I decided to take the nuxt.js course again to be indebted to Jimcoding. I felt that it wasn't a lie when he said he was 120% prepared. My motto when I was a new employee? It was 120%, so I'm glad to see you... I'm going to take the Vue 3 & Firebase lecture that you uploaded now. Please release lectures as quickly as this one when new technologies come out in the future! (Thanks to you always releasing lectures quickly, I switched from another instructor at Inflearn to you... hehe)
