Instead, the function should be given a concrete class that extends the abstract ContentCreator class. The two conditions must both hold for example, bound functions and Proxy can be constructed, but they don't have a prototype property, so they cannot be subclassed.

Any constructor that can be called with new and has the prototype property can be the candidate for the parent class.

A constructor is a special function that creates and initializes an object instance of a class.How to define and invoke Class Constructors with parameters?.How to define and invoke Class Constructors with no parameters?.What is a constructor in JavaScript Classes?.How to create objects of classes in JavaScript?.In this article, we will understand the concept of JavaScript Classes by covering the following topics: Classes got introduced in JavaScript from ES6 onwards. Similar to other OOPS based programming languages, JavaScript also supports the concept of classes. The object-oriented programming came into existence to support this functionality, which used the concept of classes to represent living types and allowed to create multiple objects of the same type. During programming, we all should have faced the scenarios when multiple instances of one type need to create.
