Don't you think 1 million won is a waste? I've heard this quite often in the camp I'm currently in. And every time, I've always said, "For my level, it's not a waste at all. Rather, I think it's cheap." I'm not a major, and I can follow iOS code, but I just gave up when it gets a little complicated or I come across grammar I don't know. Because of that, I had a hard time implementing something I had in my head. Many people asked me if there were any benefits to taking grammar classes. I'm currently conducting a camp with a lot of iOS developers, and if you know grammar, you can implement the same implementation more concisely and intuitively. And I think that such codes are helpful to both the team and to individuals. While studying grammar, I always thought, "I don't like this code. How can I make it better?" And if you adjust it one by one with the content you hear in the grammar class, I think you'll see yourself improving little by little. Of course, will your skills improve just by taking grammar classes? No, absolutely not. On the contrary, I learned a lot, but when I see that my code is full of if statements, I wonder why I studied so hard. However, I can see that I am getting better little by little by looking at my code from a week ago or two weeks ago. When I was in a slump, a teammate who was working with me said, "Your code shows that you have learned a lot," and that rekindled my passion and helped me get out of a slump that was not a slump. I really want to thank Alan.
