I was hired as a new employee and had to study RN in a hurry, so I logged into Inflearn and there was a notification for John's new lecture opening, so I hurriedly purchased it. I studied John's React before and got a job, and I'm getting help from John this time too. There aren't many up-to-date React Native lectures on Inflearn or other sites, and they don't explain in such detail. If you're in a similar situation to me, I highly recommend this lecture. It's definitely not worth 30,000 won. These days, everyone just pastes and pastes snippets, but John writes from beginning to end. And if you don't know Redux, no one makes a separate lecture. Ha, as expected, it's the best. The flow of the lecture was so good that I bought it in the morning and have been listening to it continuously until now. As expected, John's lectures that I trust and buy are the best.
