TypeScript - Basics
Abstract classes are base classes from which other classes may be derived. They may not be instantiated directly. Unlike an interface, an abstract class may contain implementation details for its non-abstract members. The abstract keyword is used to define abstract classes as well as abstract methods within an abstract class.
Abstract members (function and properties) must be defined in the derived classes and not in the abstract class. They are just sketched out.
To create a derived class from an abstract class, you must use the extends keyword.
Implements: Used with Interfaces and Classes A Class implements an Interface. Extends: An Abstract Class is inherited. A derived class extends an abstract class.
