Type System

A type system is a way programming languages classify and organize data, like categorizing objects into groups (e.g., numbers, text, dates). It helps ensure that operations and functions are used correctly—for instance, preventing you from adding text to a number accidentally. By defining how data types behave and interact, a type system improves code reliability, safety, and clarity. It acts as both a guide and a safety net, catching mistakes early and helping developers write consistent, predictable programs.
