Maps Implementation
Explore the internal implementation of Go maps and discover how to use maps with struct{} values for memory efficiency. Understand the constraints of map element addressability and practical workarounds using pointers. This lesson helps you master handling Go’s maps effectively alongside arrays and slices.

struct{} type
Go doesn’t have a set data structure (something like a map with keys
but without values, as implemented as std::set in C++ or HashSet in
C#). It’s easy enough to use a map instead. One small trick is to use
a struct{} type as a map ...
