Types

In programming, "types" define what kind of data a variable can hold, like numbers, text, or dates. They help computers understand and manage the data correctly, ensuring operations are appropriate for that data. For example, a number type enables mathematical calculations, while a text type stores written words. Types improve reliability by catching errors early and making code more organized. Think of types as categories that label data, guiding how it can be used and combined, much like how different forms of information (like a photo versus a document) are handled differently in everyday life.
