This is a lecture that will help you get a feel for Firebase very quickly and easily. The features of this lecture are as follows: 1. It is an incredibly easy lecture, 2. By the end of the lecture, front-end developers can quickly create a full-stack service without worrying about the server, 3. It is a lecture that you can learn in about a day. (3 hours at the fastest) At first, when I quickly proceeded with copy+paste, I was surprised for a few seconds, thinking, "What? Why is this lecture copy-and-paste?" lol It helps you understand sufficiently, and other concepts that are unnecessary for learning Firebase are not scattered throughout the lecture, so it is organized so that you can understand Firebase very intuitively. After studying for a few hours, become a developer who can handle the backend~ PS. I will also be waiting for the intermediate lecture +_+
