When should I use type aliases in TypeScript?

Type aliases in TypeScript are useful when you want to create a new name for a type. You can use them for primitives, unions, tuples, and more.

Can you give me an example of a type alias?

Sure! For instance, you can define a type alias for a union type like this: type StringOrNumber = string | number;.

Are there any situations where I shouldn't use type aliases?

Yes, if a type is only used once, it might be better to use an inline type definition instead of creating a type alias.

What about interfaces? How do they compare to type aliases?

Interfaces are generally preferred for defining object shapes, while type aliases can represent any type. However, they can often be used interchangeably.
