es6-set
Set collection as specified in ECMAScript6
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
