What are some examples of type safety in programming?

Type safety ensures that variables are used consistently according to their data types. For example, in Java, if you declare a variable as an integer, you cannot assign a string to it.

Can you give me more examples from different programming languages?

Sure! In TypeScript, you can define types for variables, and the compiler will throw errors if you try to assign incompatible types. In Python, using type hints can help with type safety, although it's not enforced at runtime.

What are the benefits of using type-safe languages?

Type-safe languages help catch errors at compile time, improve code readability, and make refactoring easier. They also enhance collaboration among developers by providing clear expectations for data types.

Are there any downsides to type safety?

Yes, type safety can introduce verbosity in code and may require more upfront design. It can also slow down development in some cases due to the need for type definitions.
