How does TypeScript Enum performance compare to other data structures?

TypeScript Enums are generally efficient, but their performance can vary based on usage. They are compiled to objects, which can impact performance compared to simpler data structures like arrays or objects.

What are the advantages of using Enums over plain objects?

Enums provide better readability and maintainability, as they allow you to define a set of named constants. This can help prevent errors and improve code clarity.

Are there any performance drawbacks to using Enums?

Yes, if you have a large number of Enum members, it can lead to increased memory usage. Additionally, accessing Enum values may be slightly slower than accessing plain objects.

Can you give an example of when to use Enums?

Enums are great for defining a set of related constants, like status codes or user roles, where you want to ensure that only specific values are used.
