What are some real-world examples of type inference?

Type inference is used in programming languages like TypeScript and Scala to automatically determine variable types. For instance, in TypeScript, if you declare a variable with a number, the compiler infers its type as 'number'.

Can you give me more examples in different programming languages?

Sure! In Python, type inference occurs at runtime, allowing you to assign a value to a variable without explicitly declaring its type. In languages like Haskell, type inference is done at compile time, enabling strong type checking without type annotations.

How does type inference improve code quality?

Type inference enhances code quality by reducing the need for explicit type declarations, making the code cleaner and easier to read. It also helps catch type-related errors during compilation, leading to fewer runtime errors.

Are there any drawbacks to using type inference?

Yes, while type inference simplifies code, it can sometimes lead to ambiguity or unexpected behavior if the inferred types are not what the developer intended. This can make debugging more challenging.
