Javascript Classes

While Javascript is a prototype-based language, you can still use classes.

Classes can be defined using class expressions or class declarations.

// Declaration
class MyClass {}

// Expression
const MyClass = class {}

Classes use a constructor method to instantiate the class.

Class fields are defined the same as object properties.

Private class features are prefixed with #.

Static properties (class fields and methods) provide the same function or value across instances of a class.
