I've jumped back into the job market, and since the distinction between backend and frontend seems meaningless these days, I took this course to study frontend as well. First of all, it was a perfect lecture, and I am so grateful! I was overall very satisfied with the curriculum, including the appropriate increase in difficulty across projects. For those who have just started developing, you might feel like quitting every time a new technical term pops up!! But just as Jeong-hwan said, it's better for your mental health to just pass them for now and keep going. Since these concepts are all interconnected, trying to master everything at once will lead to burnout. First, just save the keywords, and when you think, "Oh, I think this part was related to that bundling thing...?", that's when you should search for that keyword, do endless Googling, take notes, and make it your own. As you do that, you'll naturally become curious about other related keywords (e.g., browser rendering, node.js, jsx, babel, npm, vite, bundling, etc.) in a chain reaction, leading to more Googling when needed... and eventually, there comes a moment when you fully internalize it. Don't try to do everything at once; just start with "bite-sized" pieces as the course title suggests and grow from there. I wish the best of luck to everyone—including myself—who is struggling to survive as a developer, and I look forward to the next lecture!
