Create abstract methods that must be implemented by subclasses
Extend the abstract class using the 'extends' keyword to create a concrete subclass
Implement the abstract methods in the subclass
Use the abstract class as a type to ensure consistency across subclasses

Who Needs to Know This

Software engineers and developers who work with TypeScript can benefit from understanding abstract classes to improve their code organization and reusability

Key Insight

💡 Abstract classes in TypeScript allow you to define a blueprint for other classes to follow, ensuring consistency and reusability
