Introduction

Welcome to our exploration of Compound Data Structures in Go. With a foundation in basic data structures like slices and maps, we'll delve into their nested use. These structures enable us to handle complex and hierarchical data, which is typical in real-world scenarios. This lesson will guide you through a recap of the basics, the creation and modification of nested maps and slices, as well as common operations.

Recap: Maps, Slices, and Understanding Nested Structures

As a quick recap, slices in Go are flexible, dynamic arrays, while maps provide a way to store key-value pairs efficiently. Both can be nested to manage hierarchical data. Here's a simple example of a school directory using maps and slices:

Creating Nested Maps and Slices

Creating nested structures in Go is straightforward, thanks to the language's versatile nature.

Accessing Values in Nested Structures

Accessing values from nested maps or slices in Go follows similar principles as their non-nested counterparts.

Common Operations on nested Structures

Modification of nested slices and maps resembles that of their non-nested versions in Go.
