What are advanced features of enums in TypeScript?

In TypeScript, enums can have advanced features like computed members, heterogeneous enums, and const enums. Would you like to explore any specific feature?

Can you explain computed members in enums?

Sure! Computed members allow you to assign values to enum members based on expressions. For example:

enum Example {
    A = 1,
    B = A + 1,
    C = B * 2
}

Here, B is computed as 2 and C as 4. Do you want to see more examples?

What about heterogeneous enums?

Heterogeneous enums allow you to mix string and numeric values in the same enum. For instance:

enum Mixed {
    No = 0,
    Yes = 'YES'
}

This can be useful in certain scenarios. Would you like to know when to use them?

Yes, when should I use heterogeneous enums?

Heterogeneous enums can be useful when you need to represent a set of related values that include both numbers and strings, such as status codes and messages. However, they can lead to confusion, so use them judiciously. Do you have any other questions about enums?
