Is it possible to make memory constant without removing the map?

In Go, it is not possible to make a map completely constant because the built-in map type is mutable and does not support constants directly. However, you can achieve a "constant" memory effect with a map if:
- Initialize the map once and do not modify it afterwards (do not add or remove elements).
- Make the map private and provide only read methods, without methods for modification.
Example:
var constMap = map[string]int{
"one": 1,
"two": 2,
}
func GetValue(key string) (int, bool) {
val, ok := constMap[key]
return val, ok
}
Thus, although the map is not a constant, restricting access to it only for reading essentially makes it "constant" memory without deleting the map.
