What are the best practices for using enums in TypeScript?
When using enums in TypeScript, it's best to use them for a fixed set of related constants. Avoid using enums for dynamic values.
Can you explain the difference between string enums and numeric enums?
Sure! String enums allow you to assign string values to the enum members, while numeric enums assign numeric values, starting from 0 by default.
Are there any performance considerations when using enums?
Enums are generally efficient, but if you have a large number of members, consider using a union of string literals instead for better performance.
What about using enums in switch statements?
Enums work great in switch statements, as they provide a clear and type-safe way to handle different cases.
Can you give an example of a good use case for enums?
A good use case for enums is defining a set of user roles in an application, like Admin, User, and Guest, which can be easily referenced throughout the code.
