Summary
In this chapter, we learned about the basic data types of Go, including numerical data types, strings, and errors. Additionally, we learned how to group similar values using arrays and slices. Lastly, we learned about the differences between arrays and slices and why slices are more versatile than arrays, as well as pointers and generating random numbers and strings in order to generate random data.
One thing that you should remember from this chapter is that a slice is empty if its length is equal to 0. On the other hand, a slice is nil if it is equal to nil—this means that it points to no memory address. The var s []string statement creates a nil slice without allocating any memory. A nil slice is always empty—the reverse is not always true.
As far as Go strings are concerned, remember that double quotes define an interpreted string literal whereas back quotes define a raw string literal. Most of the time, you need double quotes.
