What are type constraints in programming languages?
Type constraints are rules that restrict the types of values that can be used in a given context, ensuring type safety.
Can you give examples of type constraints in languages like Java and Python?
In Java, you can use generics with type parameters, like <T extends Number>. In Python, type hints can be used with the typing module.
How do these constraints affect code performance?
Type constraints can improve performance by enabling optimizations during compilation in statically typed languages, while in dynamically typed languages, they help catch errors early.
Are there any downsides to using type constraints?
Yes, type constraints can make code more complex and less flexible, potentially leading to longer development times.
