• Class-Based Architecture - Teaches class-based programming with inheritance, visibility modifiers, abstract methods, and constructor parameter properties.
• Visibility Modifiers - Teaches TypeScript's class inheritance with public, private, and protected member visibility modifiers.
• Compile-Time Type Inspection - Explains how TypeScript removes type annotations during compilation to produce clean JavaScript.
• Generic Programming - Teaches generic programming with type parameters and constraints for reusable functions, interfaces, and classes.
• Type Parameter Constraints - Teaches generic type parameter constraints for ensuring type safety in reusable functions and classes.

• Declaration Merging - Covers TypeScript's declaration merging feature for incremental type definitions across files.
• String Literal Union Type Definitions - Teaches defining union types from string literals for compile-time validation.
• Function Decorators - Teaches wrapping methods with decorators to add orthogonal behavior like logging or timing.
• Dependency Injection - Teaches dependency injection via decorators for decoupling modules from concrete implementations.
• Type Intersection and Merging - Teaches combining multiple type definitions into one using intersection types.
