Classes are a template for creating objects. They encapsulate data with code to work on that data. Classes in JS are built on prototypes but also have some syntax and semantics that are unique to classes. For more examples and explanations, see the Using classes guide. Classes are in fact "special functions ", and just as you can define function expressions and function declarations , a class can be defined in two ways: a class expression or a class declaration. Like function expressions, class expressions may be anonymous, or have a name that's different from the variable that it's assigned to. However, unlike function declarations, class declarations have the same temporal dead zone restrictions as let or const and behave as if they are not hoisted. This is where you define class members, such as methods or constructor. The body of a class is executed in strict mode even without the "use strict" directive.
