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 them for dynamic values.
Can you give me an example of when to use an enum?
Sure! Use enums for defining a set of options, like days of the week or status codes, to improve code readability.
Are there any performance considerations with enums?
Enums in TypeScript are compiled to objects in JavaScript, which can have a slight performance overhead. Use them judiciously.
What about string enums? Are they better?
String enums are often preferred for their readability and debugging benefits, especially when the values are meaningful.
How do enums compare to union types?
Enums provide a clear structure and are easier to use in some cases, while union types offer more flexibility and can represent more complex scenarios.
