How to overtake structure in map?

Question

go

Good afternoon!
For three hours now I have been trying to figure out what kind of map this type is. As far as I understood from the Internet - an array in which instead of a numerical index - anything.
And for some reason I am convinced that describing the map is much easier and more correct than stirring up nested structures. Can someone suggest/explain/poke where to read?

Answer 1

I correctly understood the question: are you comparing map (hash table) with nested structures?
If so, do not confuse green and soft.
Mappings (aka maps) are used as unordered key-value stores with fast lookups.
Nested structures assume a hierarchy of functionality and data.
Slices (or arrays) of structures are ordered lists of functionality and data.
Not really, slices, mappings, and functions can't be keys. proof
inside map

Answer 2

What are the persuasive arguments? Each task has its own data type, somewhere map is better, somewhere nested structures

Answer 3

SilentFl , they say that this will be a bunch of nested structures, otherwise it's all described by one map. They didn't say anything else, they just left. And I hear about map for the first time in my life.
