This lecture was a very informative time where I could learn how to utilize various React libraries such as react-query, react-hook-form, and i18n, as well as React Native and Expo. I learned a lot from Kyo's restaurant app lecture using React Native CLI, and this time, I learned Expo and also gained various development know-how from the instructor. It was a very satisfying lecture, and I hope to take another lecture by Kyo in the future to learn other things. Thank you for creating such a great lecture!
