Let me give you a brief review of game production. It was helpful to learn about a framework called phaser, but I was able to experience the game production process firsthand, and understand how each function or scene effect is connected and works. In that sense, I think this lecture is a lecture that can be experienced in advance for those who dream of becoming a game developer or are curious about what a game developer is, rather than for JavaScript developers. And if I develop it a little more here, I could create my own game project. However, since it is a JavaScript library, I need to have some understanding of JavaScript. Since there is a lot of code to write in the lecture, I only explain the core code and move on, so it may be difficult for beginners to follow.
