We also talked about the text/template and html/template packages, which allow you to create plain text and HTML output based on templates. Last, we talked about the syscall standard Go package that offers advanced features.

In the next chapter, we will discuss two important Go features: interfaces and reflection. Additionally, we will talk about object-oriented programming in Go and Go type methods. All of these topics are pretty advanced, and you might find them difficult at first. However, learning more about them will unquestionably make you a better Go programmer!
