Hello, this is Lee Do-won. First of all, I would like to thank you for your interest in the lecture. This lecture was conducted on the basic understanding of RESTful API and how to use it. Regardless of the language used in the frontend, the lecture was on the RESTful API itself. There was an opinion that it would be good to add examples to practice in conjunction with recent trends such as Vue.js, React, and Angular, so I will reflect it when updating the lecture. Thank you.
