This module contains extended collection in addition to existing ECMAScript collections:

• OrderedSet is a collection similar to Set, but with a guaranteed order and indexing.
• OrderedMap is a collection similar to Map, but with a guaranteed order and indexing.
• Implementation is a collection that can associate interfaces to their relevant implementation. The collection is similar to Symbol primitive, but it does not modify the interface objects - no string or symbol properties are added to that object. A symbol is added to the implementation object to link back the interface.
• WeakOrderedSet is a collection loosly similar to OrderedSet and Array, but objects assigned to this collection are hold by weak references and can be garbage collected. Like WeakSet the collection can only store objects (not primitives), but maintains the order of the objects inside. Indexing is not supported for this collection.

Installation

To install this module, run:

npm install @dragiyski/collection

Usage

To use this module, use either shorthand syntax:

const { OrderedSet, OrderedMap } = require('@dragiyski/collection');

or include specific collection by filename:

const OrderedSet = require('@dragiyski/collection/ordered-set');

All filenames use dash-case.
