What are some programming languages that support runtime type checking?

What are some programming languages that support runtime type checking?

Some programming languages that support runtime type checking include TypeScript, Python, and Ruby. Would you like to know more about any specific language?

Can you explain how runtime type checking works in Python?

In Python, runtime type checking is done using the isinstance() function, which checks if an object is an instance of a specified class or type. This allows you to enforce type constraints during execution.

Are there any performance drawbacks to using runtime type checking?

Yes, runtime type checking can introduce overhead, as the checks are performed during execution. This can slow down performance, especially in tight loops or performance-critical applications.

What are the benefits of using languages with runtime type checking?

The benefits include increased flexibility, easier debugging, and the ability to catch type-related errors at runtime, which can enhance code reliability.
