Structuring TypeScript: Interfaces, Type Aliases, Enums, and Object Types

TypeScript enables modeling real-world data like API responses and users through interfaces, type aliases, and enums. While inline object types describe basic data shapes, interfaces provide a reusable programming structure for multiple objects sharing the same properties. Interfaces utilize semicolons for definition and support optional properties via the ?: symbol. These features collectively empower developers to build robust applications by precisely defining the structure and property types of complex objects within the TypeScript environment.
