What are the best practices for using types and interfaces in TypeScript?
When using TypeScript, it's best to use interfaces for defining object shapes and types for more complex types. Always prefer interfaces for public API definitions.
Can you explain why interfaces are preferred for public APIs?
Interfaces allow for better extensibility and can be merged, which is useful for defining contracts in public APIs.
What about using types for union types?
Types are great for creating union types and can represent more complex structures, making them ideal for scenarios where you need flexibility.
Are there any performance considerations I should be aware of?
Generally, TypeScript's type system is erased during compilation, so there are no runtime performance impacts. Focus on maintainability and clarity.
