I am a new programmer. These codes are one part of a project in the Codecademy Web Development course. At first glance, it was a bit tricky to build it because there where several ways to write these codes. However, I tried to pay attention to the importance of controlling the complexity of the program.
I would be highly grateful if you could write your opinion about it.
