difference between abstract class and interface javascript
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.

What's the difference between a Java interface and an abstract class?
Members of a Java interface are public by default. A Java abstract class can have the usual flavors of class members like private, protected, etc.. It's pretty simple actually. You can think of an interface as a class which is only allowed to have abstract methods and nothing else.
What is the difference between an interface and a class?
An interface is not allowed to define data. Another difference is that classes can only inherit one abstract class but can inherit multiple interfaces. One of the biggest differences is that if a class uses an interface it has to implement all the methods and properties declared in the interface.
