It doesn't matter. Everyone start from new and you learn it really fast 👍. I noticed that there're some ident mismatches in your code. Maybe you should use the formatter gofmt that go standard suggesting. Generally, VSCode will suggest you to install it and format the code automatically when you press ctrl+s.
