Classes
Learn how to define TypeScript classes, implement inheritance, use access modifiers, create interfaces, handle constructors, and work with abstract and static features.
Constructors
Build TypeScript class constructors with parameter properties and proper initialization to create robust object instances.
Interfaces
Discover how to define, extend, and implement TypeScript interfaces for type safety, code reusability, and consistent object shapes, while handling optional properties and combining interfaces.
Interface vs. Type
Learn when to use interfaces vs types in TypeScript and use the subtle differences between them to write more maintainable code.
Extends
Master TypeScript's extends keyword to create powerful type constraints and conditional types that adapt based on input parameters.
Extend Interface
Extend TypeScript interfaces to build composable type definitions that promote code reuse and maintainability.
Inheritance
Implement class inheritance in TypeScript with proper method overriding and access modifiers for maintainable object hierarchies.
Abstract Classes
Build robust abstract classes in TypeScript to create enforceable contracts for your class hierarchies while sharing implementation.
Decorators
Discover how to use TypeScript decorators to add metadata, implement logging, manage access control, and optimize code reusability in your applications.
Optional Chaining
Access nested object properties safely in TypeScript using optional chaining to avoid runtime null reference errors.
