| r789 | # es6-map | |||
| ## Map 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 | ||||
| It’s safest to use *es6-map* as a [ponyfill](https://ponyfill.com) – a polyfill which doesn’t touch global objects: | ||||
| ```javascript | ||||
| var Map = require('es6-map'); | ||||
| ``` | ||||
| If you want to make sure your environment implements `Map` globally, do: | ||||
| ```javascript | ||||
| require('es6-map/implement'); | ||||
| ``` | ||||
| If you strictly want to use the polyfill even if the native `Map` exists, do: | ||||
| ```javascript | ||||
| var Map = require('es6-map/polyfill'); | ||||
| ``` | ||||
| ### Installation | ||||
| $ npm install es6-map | ||||
| To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/) | ||||
| #### API | ||||
| Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-map-objects). Still if you want quick look, follow examples: | ||||
| ```javascript | ||||
| var Map = require('es6-map'); | ||||
| var x = {}, y = {}, map = new Map([['raz', 'one'], ['dwa', 'two'], [x, y]]); | ||||
| map.size; // 3 | ||||
| map.get('raz'); // 'one' | ||||
| map.get(x); // y | ||||
| map.has('raz'); // true | ||||
| map.has(x); // true | ||||
| map.has('foo'); // false | ||||
| map.set('trzy', 'three'); // map | ||||
| map.size // 4 | ||||
| map.get('trzy'); // 'three' | ||||
| map.has('trzy'); // true | ||||
| map.has('dwa'); // true | ||||
| map.delete('dwa'); // true | ||||
| map.size; // 3 | ||||
| map.forEach(function (value, key) { | ||||
| // { 'raz', 'one' }, { x, y }, { 'trzy', 'three' } iterated | ||||
| }); | ||||
| // FF nightly only: | ||||
| for (value of map) { | ||||
| // ['raz', 'one'], [x, y], ['trzy', 'three'] iterated | ||||
| } | ||||
| var iterator = map.values(); | ||||
| iterator.next(); // { done: false, value: 'one' } | ||||
| iterator.next(); // { done: false, value: y } | ||||
| iterator.next(); // { done: false, value: 'three' } | ||||
| iterator.next(); // { done: true, value: undefined } | ||||
| map.clear(); // undefined | ||||
| map.size; // 0 | ||||
| ``` | ||||
