Function components in ng

Name Description
angular.lowercase

Converts the specified string to lowercase.

angular.uppercase

Converts the specified string to uppercase.

angular.forEach

Invokes the iterator function once for each item in obj collection, which can be either an object or an array. The iterator function is invoked with iterator(value, key, obj), where value is the value of an object property or an array element, key is the object property key or array element index and obj is the obj itself. Specifying a context for the function is optional.

angular.extend

Extends the destination object dst by copying own enumerable properties from the src object(s) to dst. You can specify multiple src objects. If you want to preserve original objects, you can do so by passing an empty object as the target: var object = angular.extend({}, object1, object2). Note: Keep in mind that angular.extend does not support recursive merge (deep copy).

angular.noop

A function that performs no operations. This function can be useful when writing code in the functional style.

function foo(callback) {
  var result = calculateResult();
  (callback || angular.noop)(result);
}
angular.identity

A function that returns its first argument. This function is useful when writing code in the functional style.

angular.isUndefined

Determines if a reference is undefined.

angular.isDefined

Determines if a reference is defined.

angular.isObject

Determines if a reference is an Object. Unlike typeof in JavaScript, nulls are not considered to be objects. Note that JavaScript arrays are objects.

angular.isString

Determines if a reference is a String.

angular.isNumber

Determines if a reference is a Number.

angular.isDate

Determines if a value is a date.

angular.isArray

Determines if a reference is an Array.

angular.isFunction

Determines if a reference is a Function.

angular.isElement

Determines if a reference is a DOM element (or wrapped jQuery element).

angular.copy

Creates a deep copy of source, which should be an object or an array.

angular.equals

Determines if two objects or two values are equivalent. Supports value types, regular expressions, arrays and objects.

angular.bind

Returns a function which calls function fn bound to self (self becomes the this for fn). You can supply optional args that are prebound to the function. This feature is also known as partial application, as distinguished from function currying.

angular.toJson

Serializes input into a JSON-formatted string. Properties with leading $$ characters will be stripped since angular uses this notation internally.

angular.fromJson

Deserializes a JSON string.

angular.bootstrap

Use this function to manually start up angular application.

angular.reloadWithDebugInfo

Use this function to reload the current application with debug information turned on. This takes precedence over a call to $compileProvider.debugInfoEnabled(false).

angular.injector

Creates an injector object that can be used for retrieving services as well as for dependency injection (see dependency injection).

angular.element

Wraps a raw DOM element or HTML string as a jQuery element.

angular.module

The angular.module is a global place for creating, registering and retrieving Angular modules. All modules (angular core or 3rd party) that should be available to an application must be registered using this mechanism.
