Still, we can try answering it, using our knowledge of the Go compiler, which was discussed in the previous blog post. So, let’s take a deep dive into the

This series of blog posts is intended for those who are already familiar with the basics of Go and would like to get a deeper insight into its internals. This tutorial is dedicated to the structure of the Go source code and some internal details of the Go compiler. After reading this, you should be able to answer the following questions: What is the structure of the Go source code?How does the Go
