What are the best practices for using types in TypeScript?

When using types in TypeScript, it's important to be explicit with your types, use interfaces for object shapes, and leverage union types for flexibility.

Can you explain the difference between interfaces and type aliases?

Sure! Interfaces are primarily used for defining the shape of objects and can be extended, while type aliases can represent any type, including primitives, unions, and tuples.

How do I create a generic type in TypeScript?

You can create a generic type by using angle brackets. For example, function identity<T>(arg: T): T { return arg; } defines a generic function.

What are some common pitfalls to avoid with TypeScript types?

Common pitfalls include using any too liberally, not leveraging strict null checks, and misunderstanding type inference.
