+ *
+ * Suspending scopes from the digest cycle can have unwanted and difficult to debug results.
+ * Only use this approach if you are confident that you know what you are doing and have
+ * ample tests to ensure that bindings get updated as you expect.
+ *
+ * Some of the things to consider are:
+ *
+ * * Any external event on a directive/component will not trigger a digest while the hosting
+ * scope is suspended - even if the event handler calls `$apply()` or `$rootScope.$digest()`.
+ * * Transcluded content exists on a scope that inherits from outside a directive but exists
+ * as a child of the directive's containing scope. If the containing scope is suspended the
+ * transcluded scope will also be suspended, even if the scope from which the transcluded
+ * scope inherits is not suspended.
+ * * Multiple directives trying to manage the suspended status of a scope can confuse each other:
+ * * A call to `$suspend()` on an already suspended scope is a no-op.
+ * * A call to `$resume()` on a non-suspended scope is a no-op.
+ * * If two directives suspend a scope, then one of them resumes the scope, the scope will no
+ * longer be suspended. This could result in the other directive believing a scope to be
+ * suspended when it is not.
+ * * If a parent scope is suspended then all its descendants will be also excluded from future
+ * digests whether or not they have been suspended themselves. Note that this also applies to
+ * isolate child scopes.
+ * * Calling `$digest()` directly on a descendant of a suspended scope will still run the watchers
+ * for that scope and its descendants. When digesting we only check whether the current scope is
+ * locally suspended, rather than checking whether it has a suspended ancestor.
+ * * Calling `$resume()` on a scope that has a suspended ancestor will not cause the scope to be
+ * included in future digests until all its ancestors have been resumed.
+ * * Resolved promises, e.g. from explicit `$q` deferreds and `$http` calls, trigger `$apply()`
+ * against the `$rootScope` and so will still trigger a global digest even if the promise was
+ * initiated by a component that lives on a suspended scope.

+ *
+ * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
+ * Contextual Escaping (SCE)} services to AngularJS.
+ *
+ * For an overview of this service and the functionnality it provides in AngularJS, see the main
+ * page for {@link ng.$sce SCE}. The current page is targeted for developers who need to alter how
+ * SCE works in their application, which shouldn't be needed in most cases.
+ *
+ *
+ * AngularJS strongly relies on contextual escaping for the security of bindings: disabling or
+ * modifying this might cause cross site scripting (XSS) vulnerabilities. For libraries owners,
+ * changes to this service will also influence users, so be extra careful and document your changes.
+ *
+ *
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
+ * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
+ * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain. While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
+ * your own trusted and banned resource lists for trusting URLs used for loading AngularJS resources
+ * such as templates. Refer {@link ng.$sceDelegateProvider#trustedResourceUrlList

+ *
+ * @description
+ *
+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * ## Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+ * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+ * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * ### Overview
+ *
+ * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+ * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+ * run security checks on them (sanitizations, trusted URL resource, depending on context), or throw
+ * when it cannot guarantee the security of the result. That behavior depends strongly on contexts:
+ * HTML can be sanitized, but template URLs cannot, for instance.
+ *
+ * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+ * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+ * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+ * render the input as-is, you will need to mark it as trusted for that context before attempting
+ * to bind it.
+ *
+ * As of version 1.2, AngularJS ships with SCE enabled by default.
+ *
+ * ### In practice
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * ```
+ *
+ * ```
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
+ * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
+ * articles, etc. via bindings. (HTML is just one example of a context where rendering user
+ * controlled input creates security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?) How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
+ * any similar validation process, unless there's a good reason to trust the given value in this
+ * context. That trust is formalized with a function call. This means that as a developer, you
+ * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
+ * you just need to ensure the values you mark as trusted indeed are safe - because they were
+ * received from your server, sanitized by your library, etc. You can organize your codebase to
+ * help with this - perhaps allowing only the files in a specific directory to do this.
+ * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
+ * becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * build the trusted versions of your values.
+ *
+ * ### How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as
+ * a way to enforce the required security context in your data sink. Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
+ * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
+ * when binding without directives, AngularJS will understand the context of your bindings
+ * automatically.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
+ * simplified):
+ *
+ * ```
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ * return function(scope, element, attr) {
+ * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ * element.html(value || '');
+ * });
+ * };
+ * }];
+ * ```
+ *
+ * ### Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, AngularJS only loads templates from the same domain and protocol as the application
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
+ * protocols, you may either add them to the {@link ng.$sceDelegateProvider#trustedResourceUrlList
+ * trustedResourceUrlList} or {@link ng.$sce#trustAsResourceUrl wrap them} into trusted values.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded. This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ### This feels like too much overhead
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (e.g.
+ * `
`) just works (remember to include the
+ * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available
+ * when binding untrusted values to `$sce.HTML` context.
+ * AngularJS provides an implementation in `angular-sanitize.js`, and if you
+ * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
+ * your application.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document. You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#trustedResourceUrlList trusted resource URL list} and {@link
+ * ng.$sceDelegateProvider#bannedResourceUrlList banned resource URL list} for matching such URLs.
+ *
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ *
+ * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
+ * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
+ *
+ * **As of 1.7.0, this is no longer the case.**
+ *
+ * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
+ * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
+ * service evaluates the expressions.
+ *
+ *
+ * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
+ * functions aren't useful yet. This might evolve.
+ *
+ * ### Format of items in {@link ng.$sceDelegateProvider#trustedResourceUrlList trustedResourceUrlList}/{@link ng.$sceDelegateProvider#bannedResourceUrlList bannedResourceUrlList}
+ *
+ *
+ *
+ *
User comments
+ * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
+ * $sanitize is available. If $sanitize isn't available, this results in an error instead of an
+ * exploit.
+ *
+ *
+ * {{userComment.name}} :
+ *
+ *
+ *
+ *
+ *
+ *
+ * angular.module('mySceApp', ['ngSanitize'])
+ * .controller('AppController', ['$http', '$templateCache', '$sce',
+ * function AppController($http, $templateCache, $sce) {
+ * var self = this;
+ * $http.get('test_data.json', {cache: $templateCache}).then(function(response) {
+ * self.userComments = response.data;
+ * });
+ * self.explicitlyTrustedHtml = $sce.trustAsHtml(
+ * 'Hover over this text. ');
+ * }]);
+ *
+ *
+ *
+ * [
+ * { "name": "Alice",
+ * "htmlComment":
+ * "Is anyone reading this? "
+ * },
+ * { "name": "Bob",
+ * "htmlComment": "Yes! Am I the only other one?"
+ * }
+ * ]
+ *
+ *
+ *
+ * describe('SCE doc demo', function() {
+ * it('should sanitize untrusted values', function() {
+ * expect(element.all(by.css('.htmlComment')).first().getAttribute('innerHTML'))
+ * .toBe('Is anyone reading this? ');
+ * });
+ *
+ * it('should NOT sanitize explicitly trusted values', function() {
+ * expect(element(by.id('explicitlyTrustedHtml')).getAttribute('innerHTML')).toBe(
+ * 'Hover over this text. ');
+ * });
+ * });
+ *
+ *
+ *
+ *
+ *
+ * ## Can I disable SCE completely?
+ *
+ * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
+ * for little coding overhead. It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
+ * you are writing a library, you will cause security bugs applications using it.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ * ```
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ * // Completely disable SCE. For demonstration purposes only!
+ * // Do not use in new projects or libraries.
+ * $sceProvider.enabled(false);

+ /* Design notes on the default implementation for SCE.
+ *
+ * The API contract for the SCE delegate
+ * -------------------------------------
+ * The SCE delegate object must provide the following 3 methods:
+ *
+ * - trustAs(contextEnum, value)
+ * This method is used to tell the SCE service that the provided value is OK to use in the
+ * contexts specified by contextEnum. It must return an object that will be accepted by
+ * getTrusted() for a compatible contextEnum and return this value.
+ *
+ * - valueOf(value)
+ * For values that were not produced by trustAs(), return them as is. For values that were
+ * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
+ * trustAs is wrapping the given values into some type, this operation unwraps it when given
+ * such a value.
+ *
+ * - getTrusted(contextEnum, value)
+ * This function should return the value that is safe to use in the context specified by
+ * contextEnum or throw and exception otherwise.
+ *
+ * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+ * opaque or wrapped in some holder object. That happens to be an implementation detail. For
+ * instance, an implementation could maintain a registry of all trusted objects by context. In
+ * such a case, trustAs() would return the same object that was passed in. getTrusted() would
+ * return the same object passed in if it was found in the registry under a compatible context or
+ * throw an exception otherwise. An implementation might only wrap values some of the time based
+ * on some criteria. getTrusted() might return a value and not throw an exception for special
+ * constants or objects even if not wrapped. All such implementations fulfill this contract.
+ *
+ *
+ * A note on the inheritance model for SCE contexts
+ * ------------------------------------------------
+ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
+ * is purely an implementation details.
+ *
+ * The contract is simply this:
+ *
+ * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+ * will also succeed.
+ *
+ * Inheritance happens to capture this in a natural way. In some future, we may not use
+ * inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
+ * be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL. Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL. This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+ etc. See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers. However, the parsed components will not be set if the URL assigned did not specify
+ * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
+ * properties such as protocol, hostname, port, etc.

+ * // filters need to be forgiving so check input validity

+/**
+ * @ngdoc filter
+ * @name filter
+ * @kind function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ *
+ * **Note**: If the array contains objects that reference themselves, filtering is not possible.
+ *
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ * `array`.
+ *
+ * Can be one of:
+ *
+ * - `string`: The string is used for matching against the contents of the `array`. All strings or
+ * objects with string properties in `array` that match this string will be returned. This also
+ * applies to nested object properties.
+ * The predicate can be negated by prefixing the string with `!`.
+ *
+ * - `Object`: A pattern object can be used to filter specific properties on objects contained
+ * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ * which have property `name` containing "M" and property `phone` containing "1". A special
+ * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
+ * against any property of the object or its nested object properties. That's equivalent to the
+ * simple substring match with a `string` as described above. The special property name can be
+ * overwritten, using the `anyPropertyKey` parameter.
+ * The predicate can be negated by prefixing the string with `!`.
+ * For example `{name: "!M"}` predicate will return an array of items which have property `name`
+ * not containing "M".
+ *
+ * Note that a named property will match properties on the same level only, while the special
+ * `$` property will match properties on the same level or deeper. E.g. an array item like
+ * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
+ * **will** be matched by `{$: 'John'}`.
+ *
+ * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
+ * The function is called for each element of the array, with the element, its index, and
+ * the entire array itself as arguments.
+ *
+ * The final result is an array of those elements that the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
+ * determining if values retrieved using `expression` (when it is not a function) should be
+ * considered a match based on the expected value (from the filter expression) and actual
+ * value (from the object in the array).
+ *
+ * Can be one of:
+ *
+ * - `function(actual, expected)`:
+ * The function will be given the object value and the predicate value to compare and
+ * should return true if both values should be considered equal.
+ *
+ * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
+ * This is essentially strict comparison of expected and actual.
+ *
+ * - `false`: A short hand for a function which will look for a substring match in a case
+ * insensitive way. Primitive values are converted to strings. Objects are not compared against
+ * primitives, unless they have a custom `toString` method (e.g. `Date` objects).
+ *
+ *
+ * Defaults to `false`.
+ *
+ * @param {string} [anyPropertyKey] The special property name that matches against any property.
+ * By default `$`.
+ *
+ * @example
+
+
+
+
+ Search:
+
+ Name Phone
+ {{friend.name}}
+ {{friend.phone}}
+
+
+ Any: Name only Phone only Equality
+ Name Phone

+ *
+ * @description
+ * Formats `date` to a string based on the requested `format`.
+ *
+ * `format` string can be composed of the following elements:
+ *
+ * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ * * `'MMMM'`: Month in year (January-December)
+ * * `'MMM'`: Month in year (Jan-Dec)
+ * * `'MM'`: Month in year, padded (01-12)
+ * * `'M'`: Month in year (1-12)
+ * * `'LLLL'`: Stand-alone month in year (January-December)
+ * * `'dd'`: Day in month, padded (01-31)
+ * * `'d'`: Day in month (1-31)
+ * * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ * * `'EEE'`: Day in Week, (Sun-Sat)
+ * * `'HH'`: Hour in day, padded (00-23)
+ * * `'H'`: Hour in day (0-23)
+ * * `'hh'`: Hour in AM/PM, padded (01-12)
+ * * `'h'`: Hour in AM/PM, (1-12)
+ * * `'mm'`: Minute in hour, padded (00-59)
+ * * `'m'`: Minute in hour (0-59)
+ * * `'ss'`: Second in minute, padded (00-59)
+ * * `'s'`: Second in minute (0-59)
+ * * `'sss'`: Millisecond in second, padded (000-999)
+ * * `'a'`: AM/PM marker
+ * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
+ * * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
+ * * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
+ * * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
+ * * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
+ *
+ * `format` string can also be one of the following predefined
+ * {@link guide/i18n localizable formats}:
+ *
+ * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ * (e.g. Sep 3, 2010 12:05:08 PM)
+ * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
+ * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
+ * (e.g. Friday, September 3, 2010)
+ * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
+ * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
+ * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
+ * * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
+ * * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
+ *
+ * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
+ * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
+ * (e.g. `"h 'o''clock'"`).
+ *
+ * Any other characters in the `format` string will be output as-is.
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
+ * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ * specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ * `mediumDate` is used.
+ * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
+ * continental US time zone abbreviations, but for general use, use a time zone offset, for
+ * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+ * If not specified, the timezone of the browser will be used.

+ * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
+ * ascending order.
+ *
+ * The comparison is done using the `comparator` function. If none is specified, a default, built-in
+ * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
+ * strings alphabetically).
+ *
+ * ### Under the hood
+ *
+ * Ordering the specified `collection` happens in two phases:
+ *
+ * 1. All items are passed through the predicate (or predicates), and the returned values are saved
+ * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
+ * through a predicate that extracts the value of the `label` property, would be transformed to:
+ * ```
+ * {
+ * value: 'foo',
+ * type: 'string',
+ * index: ...
+ * }
+ * ```
+ * **Note:** `null` values use `'null'` as their type.
+ * 2. The comparator function is used to sort the items, based on the derived values, types and
+ * indices.
+ *
+ * If you use a custom comparator, it will be called with pairs of objects of the form
+ * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
+ * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
+ * second, or `1` otherwise.
+ *
+ * In order to ensure that the sorting will be deterministic across platforms, if none of the
+ * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
+ * dummy predicate that returns the item's index as `value`.
+ * (If you are using a custom comparator, make sure it can handle this predicate as well.)
+ *
+ * If a custom comparator still can't distinguish between two items, then they will be sorted based
+ * on their index using the built-in comparator.
+ *
+ * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
+ * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
+ * it to the comparator. The following rules govern the conversion:
+ *
+ * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
+ * used instead.)=} expression - A predicate (or list of
+ * predicates) to be used by the comparator to determine the order of elements.
+ *
+ * Can be one of:
+ *
+ * - `Function`: A getter function. This function will be called with each item as argument and
+ * the return value will be used for sorting.
+ * - `string`: An AngularJS expression. This expression will be evaluated against each item and the
+ * result will be used for sorting. For example, use `'label'` to sort by a property called
+ * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
+ * property.
