What are the differences between type safety and dynamic typing?

What are the differences between type safety and dynamic typing?

Type safety ensures that variables are used consistently according to their data types, while dynamic typing allows variables to change types at runtime.

Can you give examples of languages that use type safety and dynamic typing?

Sure! Java and C# are examples of statically typed languages with type safety, while Python and JavaScript are dynamically typed.

What are the advantages of using type safety?

Type safety can prevent many runtime errors, improve code readability, and enhance maintainability by catching type-related issues at compile time.

Are there any downsides to type safety?

Yes, it can lead to more verbose code and may require more upfront design, which can slow down development in some cases.

How does dynamic typing affect performance?

Dynamic typing can introduce overhead at runtime, as type checks are performed during execution, potentially leading to slower performance compared to statically typed languages.
