When transpiling constant enums, they are completely removed from the runtime application with no residual code left behind. Any instance of a constant enum is simply replaced by its value throughout the entire app. As a result, using the declare keyword with constant enums is unnecessary:
export const enum JSDocTagName {
Desc = "desc",
Id = "id",
Meaning = "meaning"
}
Unlike regular enums, constant enums cannot have certain types of complex calculated values. For example, while normal enums allow expressions like the following, constant enums do not:
const x = 1;
enum A {
Name = x,
Age = x + 1
}
If you encounter an error related to this scenario, it may be due to attempting something similar within a constant enum.
However, you can still include some basic calculations in a constant enum as long as the outcome is deterministic. This means expressions like the following are valid for constant enums:
const enum A {
Name = 1 << 0,
Age = 1 << 1,
Date = 1 << 2
}
