Summary

In this chapter, we took a big step in working with Go’s type system. We took the time to define what types are and why they are needed. We then explored each of the core types in Go. We started with the simple bool type, and we were able to show how critical it is to everything we do in our code. We then moved on to the number types. Go has lots of types for numbers, reflecting the control that Go likes to give developers when it comes to memory usage and accuracy. After numbers, we looked at how strings work and how they are closely related to the rune type. With the advent of multi-byte characters, it’s easy to make a mess of your text data. Go has provided powerful built-in features to help you get it right. Lastly, we looked at nil and how you use it within Go.

The concepts you’ve learned in this chapter have armed you with the knowledge needed to tackle Go’s more complex types, such as collections and structs. We’ll be looking at...
