+# Contributing to Lodash
+
+Contributions are always welcome. Before contributing please read the
+[code of conduct](https://jquery.org/conduct/) &
+[search the issue tracker](https://github.com/lodash/lodash/issues); your issue
+may have already been discussed or fixed in `master`. To contribute,
+[fork](https://help.github.com/articles/fork-a-repo/) Lodash, commit your changes,
+& [send a pull request](https://help.github.com/articles/using-pull-requests/).
+
+## Feature Requests
+
+Feature requests should be submitted in the
+[issue tracker](https://github.com/lodash/lodash/issues), with a description of
+the expected behavior & use case, where they’ll remain closed until sufficient interest,
+[e.g. :+1: reactions](https://help.github.com/articles/about-discussions-in-issues-and-pull-requests/),
+has been shown by the community. Before submitting a request, please search for
+similar ones in the
+[closed issues](https://github.com/lodash/lodash/issues?q=is%3Aissue+is%3Aclosed+label%3Aenhancement).
+
+## Pull Requests
+
+For additions or bug fixes you should only need to modify `lodash.js`. Include
+updated unit tests in the `test` directory as part of your pull request. Don’t
+worry about regenerating the `dist/` or `doc/` files.
+
+Before running the unit tests you’ll need to install, `npm i`,
+[development dependencies](https://docs.npmjs.com/files/package.json#devdependencies).
+Run unit tests from the command-line via `npm test`, or open `test/index.html` &
+`test/fp.html` in a web browser. The [Backbone](http://backbonejs.org/) &
+[Underscore](http://underscorejs.org/) test suites are included as well.
+
+## Contributor License Agreement
+
+Lodash is a member of the [jQuery Foundation](https://jquery.org/).
+As such, we request that all contributors sign the jQuery Foundation
+[contributor license agreement (CLA)](https://contribute.jquery.org/CLA/).
+
+For more information about CLAs, please check out Alex Russell’s excellent post,
+[“Why Do I Need to Sign This?”](https://infrequently.org/2008/06/why-do-i-need-to-sign-this/).
+
+## Coding Guidelines
+
+In addition to the following guidelines, please follow the conventions already
+established in the code.
+
+- **Spacing**:<br>
+  Use two spaces for indentation. No tabs.
+
+- **Naming**:<br>
+  Keep variable & method names concise & descriptive.<br>
+  Variable names `index`, `array`, & `iteratee` are preferable to
+  `i`, `arr`, & `fn`.
+
+- **Quotes**:<br>
+  Single-quoted strings are preferred to double-quoted strings; however,
+  please use a double-quoted string if the value contains a single-quote
+  character to avoid unnecessary escaping.
+
+- **Comments**:<br>
+  Please use single-line comments to annotate significant additions, &
+  [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for
+  functions.
+
+Guidelines are enforced using [JSCS](https://www.npmjs.com/package/jscs):
+```bash
+$ npm run style
+```
+
+## Tips
+
+You can opt-in to a pre-push git hook by adding an `.opt-in` file to the root of
+the project containing:
+```txt
+pre-push
+```
+
+With that, when you `git push`, the pre-push git hook will trigger and execute
+`npm run validate`.

+# lodash v4.13.1
+
+[Site](https://lodash.com/) |
+[Docs](https://lodash.com/docs) |
+[FP Guide](https://github.com/lodash/lodash/wiki/FP-Guide) |
+[Contributing](https://github.com/lodash/lodash/blob/4.13.1/.github/CONTRIBUTING.md) |

+[Code of Conduct](https://jquery.org/conduct/) |
+[Twitter](https://twitter.com/bestiejs) |
+[Chat](https://gitter.im/lodash/lodash)
+
+The [Lodash](https://lodash.com/) library exported as a [UMD](https://github.com/umdjs/umd) module.
+
+Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli):
+```bash
+$ npm run build
+$ lodash -o ./dist/lodash.js
+$ lodash core -o ./dist/lodash.core.js
+```
+
+## Download
+
+Lodash is released under the [MIT license](https://raw.githubusercontent.com/lodash/lodash/4.13.1/LICENSE) & supports [modern environments](#support).<br>
+Review the [build differences](https://github.com/lodash/lodash/wiki/build-differences) & pick one that’s right for you.
+
+ * [Core build](https://raw.githubusercontent.com/lodash/lodash/4.13.1/dist/lodash.core.js) ([~4 kB gzipped](https://raw.githubusercontent.com/lodash/lodash/4.13.1/dist/lodash.core.min.js))
+ * [Full build](https://raw.githubusercontent.com/lodash/lodash/4.13.1/dist/lodash.js) ([~22 kB gzipped](https://raw.githubusercontent.com/lodash/lodash/4.13.1/dist/lodash.min.js))
+ * [CDN copies](https://www.jsdelivr.com/projects/lodash)
+
+## Why Lodash?
+
+Lodash makes JavaScript easier by taking the hassle out of working with arrays,<br>
+numbers, objects, strings, etc. Lodash’s modular methods are great for:
+
+* Iterating arrays, objects, & strings
+* Manipulating & testing values
+* Creating composite functions
+
+## Module Formats
+
+Lodash is available in a [variety of builds](https://lodash.com/custom-builds) & module formats.
+
+ * [lodash](https://www.npmjs.com/package/lodash) & [per method packages](https://www.npmjs.com/browse/keyword/lodash-modularized)
+ * [lodash-amd](https://www.npmjs.com/package/lodash-amd)
+ * [lodash-es](https://www.npmjs.com/package/lodash-es) & [babel-plugin-lodash](https://www.npmjs.com/package/babel-plugin-lodash)
+ * [lodash/fp](https://github.com/lodash/lodash/tree/4.13.1-npm/fp)

+   * Creates a `lodash` object which wraps `value` to enable implicit method
+   * chain sequences. Methods that operate on and return arrays, collections,

+   * or may return a primitive value will automatically end the chain sequence
+   * and return the unwrapped value. Otherwise, the value must be unwrapped
+   * with `_#value`.
+   *
+   * Explicit chain sequences, which must be unwrapped with `_#value`, may be

+   * The execution of chained methods is lazy, that is, it's deferred until

+   *
+   * Lazy evaluation allows several methods to support shortcut fusion.
+   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+   * the creation of intermediate arrays and can greatly reduce the number of
+   * iteratee executions. Sections of a chain sequence qualify for shortcut
+   * fusion if the section is applied to an array of at least `200` elements
+   * and any iteratees accept only one argument. The heuristic for whether a

+
+Creates a debounced function that delays invoking `func` until after `wait`
+milliseconds have elapsed since the last time the debounced function was
+invoked. The debounced function comes with a `cancel` method to cancel
+delayed `func` invocations and a `flush` method to immediately invoke them.
+Provide an options object to indicate whether `func` should be invoked on
+the leading and/or trailing edge of the `wait` timeout. The `func` is invoked
+with the last arguments provided to the debounced function. Subsequent calls
+to the debounced function return the result of the last `func` invocation.
+<br>
+<br>
+**Note:** If `leading` and `trailing` options are `true`, `func` is invoked
+on the trailing edge of the timeout only if the debounced function is
+invoked more than once during the `wait` timeout.

+Creates a throttled function that only invokes `func` at most once per
+every `wait` milliseconds. The throttled function comes with a `cancel`
+method to cancel delayed `func` invocations and a `flush` method to
+immediately invoke them. Provide an options object to indicate whether
+`func` should be invoked on the leading and/or trailing edge of the `wait`
+timeout. The `func` is invoked with the last arguments provided to the
+throttled function. Subsequent calls to the throttled function return the
+result of the last `func` invocation.
+<br>
+<br>
+**Note:** If `leading` and `trailing` options are `true`, `func` is
+invoked on the trailing edge of the timeout only if the throttled function
+is invoked more than once during the `wait` timeout.
+<br>
+<br>
+See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
+for details over the differences between `_.throttle` and `_.debounce`.
+
+#### Since
+0.1.0
+#### Arguments
+1. `func` *(Function)*: The function to throttle.
+2. `[wait=0]` *(number)*: The number of milliseconds to throttle invocations to.
+3. `[options={}]` *(Object)*: The options object.
+4. `[options.leading=true]` *(boolean)*: Specify invoking on the leading edge of the timeout.
+5. `[options.trailing=true]` *(boolean)*: Specify invoking on the trailing edge of the timeout.
+
+#### Returns
+*(Function)*: Returns the new throttled function.
+
+#### Example
+```js
+// Avoid excessively updating the position while scrolling.
+jQuery(window).on('scroll', _.throttle(updatePosition, 100));
+
+// Invoke `renewToken` when the click event is fired, but not more than once every 5 minutes.
+var throttled = _.throttle(renewToken, 300000, { 'trailing': false });
+jQuery(element).on('click', throttled);
+
+// Cancel the trailing throttled invocation.
+jQuery(window).on('popstate', throttled.cancel);

+
+Creates a `lodash` object which wraps `value` to enable implicit method
+chain sequences. Methods that operate on and return arrays, collections,
+and functions can be chained together. Methods that retrieve a single value
+or may return a primitive value will automatically end the chain sequence
+and return the unwrapped value. Otherwise, the value must be unwrapped
+with `_#value`.
+<br>
+<br>
+Explicit chain sequences, which must be unwrapped with `_#value`, may be
+enabled using `_.chain`.
+<br>
+<br>
+The execution of chained methods is lazy, that is, it's deferred until
+`_#value` is implicitly or explicitly called.
+<br>
+<br>
+Lazy evaluation allows several methods to support shortcut fusion.
+Shortcut fusion is an optimization to merge iteratee calls; this avoids
+the creation of intermediate arrays and can greatly reduce the number of
+iteratee executions. Sections of a chain sequence qualify for shortcut
+fusion if the section is applied to an array of at least `200` elements
+and any iteratees accept only one argument. The heuristic for whether a
+section qualifies for shortcut fusion is subject to change.
+<br>
+<br>
+Chaining is supported in custom builds as long as the `_#value` method is
+directly or indirectly included in the build.
+<br>
+<br>
+In addition to lodash methods, wrappers have `Array` and `String` methods.
+<br>
+<br>
+The wrapper `Array` methods are:<br>
+`concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`

+## lodash/fp
+
+The `lodash/fp` module promotes a more
+[functional programming](https://en.wikipedia.org/wiki/Functional_programming)
+(FP) friendly style by exporting an instance of `lodash` with its methods wrapped
+to produce immutable auto-curried iteratee-first data-last methods.
+
+## Installation
+
+In a browser:
+```html
+<script src='path/to/lodash.js'></script>
+<script src='path/to/lodash.fp.js'></script>
+<script>
+// Loading `lodash.fp.js` converts `_` to its fp variant.
+_.defaults({ 'a': 2, 'b': 2 })({ 'a': 1 });
+// → { 'a: 1, 'b': 2 }
+
+// Use `noConflict` to restore the pre-fp variant.
+var fp = _.noConflict();
+
+_.defaults({ 'a': 1 }, { 'a': 2, 'b': 2 });
+// → { 'a: 1, 'b': 2 }
+fp.defaults({ 'a': 2, 'b': 2 })({ 'a': 1 });
+// → { 'a: 1, 'b': 2 }
+</script>
+```
+
+In Node.js:
+```js
+// Load the fp build.
+var fp = require('lodash/fp');
+
+// Load a method category.
+var object = require('lodash/fp/object');
+
+// Load a single method for smaller builds with browserify/rollup/webpack.
+var extend = require('lodash/fp/extend');
+```
+
+## Mapping
+
+Immutable auto-curried iteratee-first data-last methods sound great, but what
+does that really mean for each method? Below is a breakdown of the mapping used
+to convert each method.
+
+#### Capped Iteratee Arguments
+
+Iteratee arguments are capped to avoid gotchas with variadic iteratees.
+```js
+// The `lodash/map` iteratee receives three arguments:
+// (value, index|key, collection)
+_.map(['6', '8', '10'], parseInt);
+// → [6, NaN, 2]
+
+// The `lodash/fp/map` iteratee is capped at one argument:
+// (value)
+fp.map(parseInt)(['6', '8', '10']);
+// → [6, 8, 10]
+```
+
+Methods that cap iteratees to one argument:<br>
+<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 1)))) %>
+
+Methods that cap iteratees to two arguments:<br>
+<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 2)))) %>
+
+The iteratee of `mapKeys` is invoked with one argument: (key)
+
+#### Fixed Arity
+
+Methods have fixed arities to support auto-currying.
+```js
+// `lodash/padStart` accepts an optional `chars` param.
+_.padStart('a', 3, '-')
+// → '--a'
+
+// `lodash/fp/padStart` does not.
+fp.padStart(3)('a');
+// → '  a'
+fp.padCharsStart('-')(3)('a');
+// → '--a'
+```
+
+Methods with a fixed arity of one:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[1], _.keys(mapping.skipFixed))) %>
+
+Methods with a fixed arity of two:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[2], _.keys(mapping.skipFixed))) %>
+
+Methods with a fixed arity of three:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[3], _.keys(mapping.skipFixed))) %>
+
+Methods with a fixed arity of four:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[4], _.keys(mapping.skipFixed))) %>
+
+#### Rearranged Arguments
+
+Method arguments are rearranged to make composition easier.
+```js
+// `lodash/filter` is data-first iteratee-last:
+// (collection, iteratee)
+var compact = _.partial(_.filter, _, Boolean);
+compact(['a', null, 'c']);
+// → ['a', 'c']
+
+// `lodash/fp/filter` is iteratee-first data-last:
+// (iteratee, collection)
+var compact = fp.filter(Boolean);
+compact(['a', null, 'c']);
+// → ['a', 'c']
+```
+
+##### Most methods follow these rules
+
+A fixed arity of two has an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[2]) %>
+
+A fixed arity of three has an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[3]) %>
+
+A fixed arity of four has an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[4]) %>
+
+##### Exceptions to the rules
+
+Methods that accept an array of arguments as their second parameter:<br>
+<%= toFuncList(_.keys(mapping.methodSpread)) %>
+
+Methods with unchanged argument orders:<br>
+<%= toFuncList(_.keys(mapping.skipRearg)) %>
+
+Methods with custom argument orders:<br>
+<%= _.map(_.keys(mapping.methodRearg), function(methodName) {
+  var orders = mapping.methodRearg[methodName];
+  return ' * `_.' + methodName + '` has an order of ' + toArgOrder(orders);
+}).join('\n') %>
+
+#### New Methods
+
+Not all variadic methods have corresponding new method variants. Feel free to
+[request](https://github.com/lodash/lodash/blob/master/.github/CONTRIBUTING.md#feature-requests)
+any additions.
+
+Methods created to accommodate Lodash’s variadic methods:<br>
+<%= toFuncList(_.keys(mapping.remap)) %>
+
+#### Aliases
+
+There are <%= _.size(mapping.aliasToReal) %> method aliases:<br>
+<%= _.map(_.keys(mapping.aliasToReal).sort(), function(alias) {
+  var realName = mapping.aliasToReal[alias];
+  return ' * `_.' + alias + '` is an alias of `_.' + realName + '`';
+}).join('\n') %>
+
+## Placeholders
+
+The placeholder argument, which defaults to `_`, may be used to fill in method
+arguments in a different order. Placeholders are filled by the first available
+arguments of the curried returned function.
+```js
+// The equivalent of `2 > 5`.
+_.gt(2)(5);
+// → false
+
+// The equivalent of `_.gt(5, 2)` or `5 > 2`.
+_.gt(_, 2)(5);
+// → true
+```
+
+## Chaining
+
+The `lodash/fp` module **does not** convert chain sequence methods. See
+[Izaak Schroeder’s article](https://medium.com/making-internets/why-using-chain-is-a-mistake-9bc1f80d51ba)
+on using functional composition as an alternative to method chaining.
+
+## Convert
+
+Although `lodash/fp` & its method modules come pre-converted, there are times
+when you may want to customize the conversion. That’s when the `convert` method
+comes in handy.
+```js
+// Every option is `true` by default.
+var _fp = fp.convert({
+  // Specify capping iteratee arguments.
+  'cap': true,
+  // Specify currying.
+  'curry': true,
+  // Specify fixed arity.
+  'fixed': true,
+  // Specify immutable operations.
+  'immutable': true,
+  // Specify rearranging arguments.
+  'rearg': true
+});
+
+// The `convert` method is available on each method too.
+var mapValuesWithKey = fp.mapValues.convert({ 'cap': false });
+
+// Here’s an example of disabling iteratee argument caps to access the `key` param.
+mapValuesWithKey(function(value, key) {
+  return key == 'a' ? -1 : value;
+})({ 'a': 1, 'b': 1 });
+// => { 'a': -1, 'b': 1 }
+```
+
+Manual conversions are also possible with the `convert` module.
+```js
+var convert = require('lodash/fp/convert');
+
+// Convert by name.
+var assign = convert('assign', require('lodash.assign'));
+
+// Convert by object.
+var fp = convert({
+  'assign': require('lodash.assign'),
+  'chunk': require('lodash.chunk')
+});
+
+// Convert by `lodash` instance.
+var fp = convert(lodash.runInContext());
+```
+
+## Tooling
+
+Use [eslint-plugin-lodash-fp](https://www.npmjs.com/package/eslint-plugin-lodash-fp)
+to help use `lodash/fp` more efficiently.

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.

+
+    This file creates a global JSON object containing two methods: stringify
+    and parse.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or '&nbsp;'),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 ? '0' + n : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date ?
+                    'Date(' + this[key] + ')' : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&
+                        value.slice(0, 5) === 'Date(' &&

+
+
+    This file creates a global JSON object containing two methods: stringify
+    and parse. This file is provides the ES5 JSON capability to ES3 systems.
+    If a project might run on IE8 or earlier, then this file should be included.
+    This file does nothing on ES5 systems.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or '&nbsp;'),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 
+                            ? '0' + n 
+                            : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date 
+                    ? 'Date(' + this[key] + ')' 
+                    : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&
