This is where you define class members, such as methods or constructor.\n\nThe body of a class is executed in strict mode even without the \"use strict\" directive.\n\nA class element can be characterized by three aspects\n\nKind: Getter, setter, method, or field Location: Static or instance Visibility: Public or private\n\nTogether, they add up to 16 possible combinations. To divide the reference more logically and avoid overlapping content, the different elements are introduced in detail in different pages\n\nMethod definitions : Public instance method getter : Public instance getter setter : Public instance setter Public class fields : Public instance field static : Public static method, getter, setter, and field Private elements : Everything that's private\n\n> [!NOTE] > Private elements have the restriction that all private names declared in the same class must be unique. All other public properties do not have this restriction — you can have multiple public properties with the same name, and the last one overwrites the others. This is the same behavior as in object initializers.\n\nIn addition, there are two special class element syntaxes: constructor and static initialization blocks, with their own references.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
