What is constructor in JavaScript

The constructor is invoked whenever an object of its associated class is created. It is called constructor because it constructs the values of date members of the class . A constructor can never return any value. Hence, it is written with no return type (even void is not written).

Constructors are special class functions which performs initialization of every object . The Compiler calls the Constructor whenever an object is created. Constructors initialize values to object members after storage is allocated to the object. Whereas, Destructor on the other hand is used to destroy the class object.

A constructor in Java is a special method that is used to initialize objects . The constructor is called when an object of a class is created.
