When to use map vs struct in golang

The time to use a Map:

1. All keys must be the same type
2. All values must be the same type
3. Keys are indexed – we can iterate over them
4. Use to represent a collection of related properties
5. Don’t need to know all the keys at compile time
6. Reference Type

The time to use a struct

1. Values can be different type
2. Keys don’t support indexing
3. You need to know all the different fields at compile time
4. Use to represent a “thing” with a lot of different properties
5. Value Type
