OOjs/nan

OOjs (short for "Object-oriented JavaScript") is a JavaScript library for working with objects. Features include, , and additional utilities for working with objects and arrays. It also provides an EventEmitter mixin for event-driven programming, and a factory pattern for decoupling consumers of functionality from any particular class's implementation.

Extend prototype and static methods and properties of child constructor from a parent constructor.

Copy prototype and static methods and properties to a child constructor from a parent constructor.

Initialize a base class to be inherited by, or mixed into, a child class. Only required for classes that do not inherit or mixin other classes.

Allow event handlers to be attached, called when events occur, and detached.

Provide a simple map interface for associating arbitrary data with a symbolic name.

Registry of classes with instantiation abstraction.

See the API documentation for a complete reference of available utilities.

Kiam-iông-sìng
OOjs is optimised for modern ECMAScript 5 environments. The source code is compatible with the older ECMAScript 3 engine (such as in older versions of Internet Explorer, broadly speaking IE8 and before), but users need a polyfill to provide required ECMAScript 5 methods.

It is packaged to be run in either Web browsers or Node.js.

Bīng-miâ khong-kan
In the presence of a module system, such as in Node.js, OOjs exports all of its classes and methods. In other environments, such as Web browsers, a global variable is created named. You may access  the same way you would access   or.

If you are using eslint, you should add the following to your  file.
