How do I build a string in Golang?

Building a string seems trivial, and it generally is, but it’s a great way to dive into further to understand some of the basics around what makes Golang so interesting.

First of all, let’s note that a string in Golang is immutable. That means whenever you want to append to a string, the existing string plus what you’re appending needs to be copied to a new string in memory. This means that when optimizing code, we need to be mindful when we write code that performs these actions many times.
