set-extended

This module's aim is to expand the already available functionalities of the Set Class in JS to cover most of the usual operators when using applied Set Theory, such as: Union, Intersection or Symetric Difference of sets, Power Set, Cartesian Product, and so on.

Installation

set-extended is available on npm package manager.

npm install set-extended

Usage

First, import the module. I like to call it SuperSet, as it gives super powers to the Set class.

const SuperSet = require('set-extended');

Evaluate if a set is a subset of a set:

 MySet.subsetOf(A)
