When should I use type aliases in TypeScript?

Type aliases are useful when you want to give a name to a specific type, especially for complex types or unions.

Can you give me an example of a type alias?

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

Are there any downsides to using type aliases?

One downside is that type aliases can sometimes make the code less readable if overused or used inappropriately.

How do type aliases differ from interfaces?

Type aliases can represent any valid type, while interfaces are specifically for object shapes and can be extended.
