How can I implement gradual typing in my programming language?

What is gradual typing and how can I implement it in my programming language?

Gradual typing is a type system that allows you to mix static and dynamic typing. You can implement it by defining type annotations and using a type checker that can handle both types.

Can you give me an example of how to add type annotations?

Sure! In a language like TypeScript, you can add type annotations like this: let x: number = 5; This tells the compiler that x should always be a number.

What are the benefits of using gradual typing?

The benefits include increased flexibility, better error detection during development, and the ability to gradually adopt typing in existing codebases.

Are there any downsides to gradual typing?

Yes, potential downsides include added complexity in the type system and possible performance overhead due to type checking.
