Go language Array

This is a created article in which the information may have evolved or changed.

Introduced

• Array is a value type, and Slice and Map are reference types. They are very different, especially when parameters are passed.
• In addition, Slice and MAP variables simply declare that they do not work, and must also allocate space (that is, initialization, initialization) before they can be used.
• Third, Slice and Map the memory allocations of these reference variables do not need you to worry about, because Golang is a GC mechanism (garbage collection mechanism)
