What are some common mistakes in type inference?

Common mistakes in type inference include misunderstanding type coercion, ignoring type annotations, and misusing generics.

Can you explain type coercion and how it leads to mistakes?

Type coercion is when a value is automatically converted to a different type. This can lead to unexpected behavior if not handled properly.

What are type annotations and why are they important?

Type annotations explicitly define the type of a variable, helping to catch errors early and improve code readability.

How do generics contribute to type inference mistakes?

Generics can complicate type inference if not used correctly, leading to type mismatches and runtime errors.
