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:

javascript 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:

javascript var Set = require("es6-set");

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

javascript 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:

```javascript 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 ```
