What are the best practices for dynamic type checking in programming?

Dynamic type checking is crucial for ensuring type safety at runtime. Best practices include using type assertions, leveraging type guards, and maintaining clear documentation.

Can you explain what type assertions are?

Type assertions allow you to specify a type for a variable, telling the compiler to treat it as that type. This is useful when you know more about the variable than the compiler does.

What are type guards?

Type guards are functions or expressions that check the type of a variable at runtime, helping to narrow down the type and ensure safe operations.

How can I implement these practices in my code?

You can implement these practices by using conditional checks for type guards, applying type assertions where necessary, and writing unit tests to validate type behavior.
