Js constructor

A constructor is a special type of member function that is called automatically when an object is created . In C++, a constructor has the same name as that of the class and it does not have a return type. For example, class Wall { public: // create a constructor Wall() { // code } };

A constructor method is a special function that creates an instance of the class . Typically, constructor methods accept input arguments to assign the data stored in properties and return an initialized object. For a basic example, see Creating a Simple Class.

In class-based object-oriented programming, a constructor (abbreviation: ctor) is a special type of subroutine called to create an object . It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables.
