How does type inference work?

Can you explain how type inference works in programming languages?

Sure! Type inference is a feature in some programming languages where the compiler automatically determines the type of a variable based on its value or context.

Which languages use type inference?

Languages like Haskell, Scala, and TypeScript use type inference to simplify code and reduce the need for explicit type annotations.

What are the benefits of using type inference?

The main benefits include cleaner code, reduced verbosity, and the ability to catch type errors at compile time without explicit type declarations.

Are there any downsides to type inference?

Yes, one downside is that it can sometimes lead to less readable code, especially for complex types, making it harder for developers to understand the code at a glance.
