What are the common pitfalls in type inference?

Common pitfalls in type inference include type ambiguity, overgeneralization, and missing type annotations.

Can you explain type ambiguity with an example?

Sure! Type ambiguity occurs when a variable can be interpreted as multiple types. For instance, in a function that accepts both strings and numbers, the type of the input may not be clear.

What about overgeneralization?

Overgeneralization happens when a type inference system assumes a broader type than intended, which can lead to runtime errors.

How can I avoid these pitfalls in my code?

To avoid these pitfalls, use explicit type annotations, keep your code modular, and leverage type-checking tools.
