Type Systems

A type system is a set of rules in programming that labels data with specific categories—like numbers, text, or dates—to ensure correct processing. It helps prevent errors by verifying that operations are appropriate for each data type, such as avoiding adding a number to text. Think of it as a strict organizer that classifies and manages data to keep programs running smoothly and reliably. This system enhances safety, readability, and maintainability of code by clearly defining how different data can be used and interacted with.
