what is class in javascript

In JavaScript, a class is a template for creating objects. It encapsulates data with code to work on that data. Classes in JavaScript are built on prototypes but also have some syntax and semantics that are unique to JavaScript. They were introduced in ECMAScript 2015 (ES6) and are essentially "special functions" that can be defined using class expressions or class declarations. A class in JavaScript is not an object itself, but a blueprint for objects. It is used to create multiple objects with similar properties and methods. The class statement initiates a JavaScript class, and properties and methods are assigned in the constructor() method, which is called each time a class object is initialized
