    es6-set

    Set collection as specified in ECMAScript6

    Warning:
    v0.1 version does not ensure O(1) algorithm complexity (but O(n)). This shortcoming will be addressed in v1.0

    Usage

    If you want to make sure your environment implements Set, do:

    require('es6-set/implement');

    If you'd like to use native version when it exists and fallback to polyfill if it doesn't, but without implementing Set on global scope, do:

    var Set = require('es6-set');

    If you strictly want to use polyfill even if native Set exists, do:

    var Set = require('es6-set/polyfill');

    Installation

    $ npm install es6-set
    

    To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: Browserify, Webmake or Webpack

    API

    Best is to refer to specification. Still if you want quick look, follow examples:

    var Set = require('es6-set');
     
    var set = new Set(['raz', 'dwa', {}]);
     
    set.size;          // 3
    set.has('raz');    // true
    set.has('foo');    // false
    set.add('foo');    // set
    set.size           // 4
    set.has('foo');    // true
    set.has('dwa');    // true
    set.delete('dwa'); // true
    set.size;          // 3
     
    set.forEach(function (value) {
     // 'raz', {}, 'foo' iterated
    });
     
    // FF nightly only:
    for (value of set) {
     // 'raz', {}, 'foo' iterated
    }
     
    var iterator = set.values();
     
    iterator.next(); // { done: false, value: 'raz' }
    iterator.next(); // { done: false, value: {} }
    iterator.next(); // { done: false, value: 'foo' }
    iterator.next(); // { done: true, value: undefined }
     
    set.clear(); // undefined
    set.size; // 0
