Type checking in Python enhances code clarity and reliability. We catch errors early and maintain high software quality by using type hints and one or more type checkers. This article covers the benefits of type hints, and how to install and run mypy, pyright, and pyre.
Discover how phantom types enhance the builder pattern in Scala, ensuring all steps are complete before object creation. See practical examples like a database connection builder and learn how compile-time checks improve type safety and prevent errors.
Discover the advantages of union types and flow typing in Scala 3. Learn how union types reduce verbosity and runtime overhead compared to Either, and how flow typing enhances type safety and code readability. Learn to handle null values explicitly.
Learn about Scala 3's explicit nulls feature, which improves type safety by making nullability part of the type system. Discover how Null is no longer connected to AnyRef, reducing null pointer exceptions and enhancing code robustness. Explore the benefits of Scala 3's updated type hierarchy.
