Tại một vài thời điểm, bạn sẽ bắt đầu định nghĩa hàm, bạn có các tham số...

Nhưng sau đó bạn phải gọi "phương thức chuyển đổi kí tự đầu tiên sang kiểu chữ hoa".

Có phải là `upper`? Có phải là `uppercase`? `first_uppercase`? `capitalize`?

Sau đó, bạn thử hỏi người bạn cũ của mình, autocompletion của trình soạn thảo.
