JavaScript constructor not working

The compiler automatically provides a public no-argument constructor for any class without constructors . This is called the default constructor. If we do explicitly declare a constructor of any form, then this automatic insertion by the compiler won’t occur.

Creating and using constructors A constructor is useful when you want to create multiple similar objects with the same properties and methods . It’s a convention to capitalize the name of constructors to distinguish them from regular functions.

If you don’t define a constructor for the class, a default one is created. The default constructor is an empty function, which doesn’t modify the instance. At the same time, a JavaScript class can have up to one constructor .11 Ara 2019
