abstract class vs interface js

What is the difference between a class and an interface in JavaScript?
An interface doesn't exist at all at runtime, so it is not possible to make an introspection. It is the classic JavaScript way to deal with object programming, but with a good control at compile time of the defined contracts. A class is both a contract and the implementation of a factory. An abstract class is also an implementation but incomplete.
What are abstract classes in JavaScript?
Abstract classes are a traditional OOP approach, which is not traditional in JavaScript. Both approaches allow the same things to be done. They are two different ways of solving a problem. A bigger difference in TypeScript is that (abstract) classes are available at runtime, while interfaces are compile time only.
What are the differences between interfaces and abstract classes?
The following table illustrates the differences between interfaces and abstract classes: Define contractual structure. Provide common functionality and structure. Contains only method signatures. Can contain implemented methods and abstract methods. Supports multiple interface implementation. Supports single class inheritance.
Can a class implement multiple interfaces?
A class can implement multiple interfaces. A child class can define abstract methods with the same or less restrictive visibility, whereas class implementing an interface must define all interface methods as public. Abstract Classes can have constructors but not interfaces. Interfaces from Java 9 have private static methods.
