Object and Type System

An object is a fundamental building block in programming, representing a specific thing or concept with properties (attributes) and actions (methods). Think of an object as a digital version of something real, like a car with color and model, that can perform tasks like starting or stopping. The type system is the set of rules that defines what kinds of objects exist and how they can interact. It ensures that objects are used correctly, preventing errors by checking that operations are performed on compatible types, much like grammar rules ensure clear communication.
