class

A class is a type of function, but instead of using the keyword 'function', keyword 'class' is used to initiate it, and the properties are assigned inside a constructor() method. The constructor() method is called each time the class object is initialized.

Example-1

In the following example, a class called 'company' is created and inside a constructor() method the name of the company is assigned and displayed the result in the output.
