+# d
+
+## Property descriptor factory
+
+_Originally derived from [d](https://github.com/medikoo/d) package._
+
+Defining properties with descriptors is very verbose:
+
+```javascript
+var Account = function () {};
+Object.defineProperties(Account.prototype, {
+  deposit: {
+    value: function () { /* ... */ },
+    configurable: true,
+    enumerable: false,
+    writable: true
+  },
+  withdraw: {
+    value: function () { /* ... */ },
+    configurable: true,
+    enumerable: false,
+    writable: true
+  },
+  balance: { get: function () { /* ... */ }, configurable: true, enumerable: false }
+});
+```
+
+D cuts that to:
+
+```javascript
+var d = require("d");
+
+var Account = function () {};
+Object.defineProperties(Account.prototype, {
+  deposit: d(function () { /* ... */ }),
+  withdraw: d(function () { /* ... */ }),
+  balance: d.gs(function () { /* ... */ })
+});
+```
+
+By default, created descriptor follow characteristics of native ES5 properties, and defines values as:
+
+```javascript
+{ configurable: true, enumerable: false, writable: true }
+```
+
+You can overwrite it by preceding _value_ argument with instruction:
+
+```javascript
+d("c", value); // { configurable: true, enumerable: false, writable: false }
+d("ce", value); // { configurable: true, enumerable: true, writable: false }
+d("e", value); // { configurable: false, enumerable: true, writable: false }
+
+// Same way for get/set:
+d.gs("e", value); // { configurable: false, enumerable: true }
+```
+
+### Installation
+
+    $ npm install d
+
+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/)
+
+### Other utilities
+
+#### autoBind(obj, props) _(d/auto-bind)_
+
+Define methods which will be automatically bound to its instances
+
+```javascript
+var d = require('d');
+var autoBind = require('d/auto-bind');
+
+var Foo = function () { this._count = 0; };
+Object.defineProperties(Foo.prototype, autoBind({
+  increment: d(function () { ++this._count; });
+}));
+
+var foo = new Foo();
+
+// Increment foo counter on each domEl click
+domEl.addEventListener('click', foo.increment, false);
+```
+
+#### lazy(obj, props) _(d/lazy)_
+
+Define lazy properties, which will be resolved on first access
+
+```javascript
+var d = require("d");
+var lazy = require("d/lazy");
+
+var Foo = function () {};
+Object.defineProperties(Foo.prototype, lazy({ items: d(function () { return []; }) }));
+
+var foo = new Foo();
+foo.items.push(1, 2); // foo.items array created and defined directly on foo
+```

+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.

+- Access `Symbol` from a global object. Makes implementation more bulletproof, as it's safe against shadowing the `Symbol` variable e.g. in script scope, or as it's practiced by some bundlers as Webpack (thanks [@cyborgx37](https://github.com/medikoo/es6-symbol/pull/30))
+- Switch license from MIT to ISC

+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](https://tc39.github.io/ecma262/#sec-symbol-objects)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to [ponyfill](https://ponyfill.com) if it doesn't, use _es6-symbol_ as following:
+
+```javascript
+var Symbol = require("es6-symbol");
+```
+
+If you want to make sure your environment implements `Symbol` globally, do:
+
+```javascript
+require("es6-symbol/implement");
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require("es6-symbol/polyfill");
+```
+
+#### API
+
+Best is to refer to [specification](https://tc39.github.io/ecma262/#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require("es6-symbol");
+
+var symbol = Symbol("My custom symbol");
+var x = {};
+
+x[symbol] = "foo";
+console.log(x[symbol]);
+("foo");
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while (!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+
+#### NPM
+
+In your project path:
+
+    $ npm install es6-symbol
+
+##### Browser
+
+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/)
+
+## Tests
+
+    $ npm test
+
+## Security contact information
+
