This object implements four methods similar to the angular 1 dependency injector

UI-Router evolved from an angular 1 library to a framework agnostic library. However, some of the ui-router-core code uses these ng1 style APIs to support ng1 style dependency injection.

This object provides a naive implementation of a globally scoped dependency injection system. It supports the following DI approaches:

Function parameter names

A function's .toString() is called, and the parameter names are parsed. This only works when the parameter names aren't "mangled" by a minifier such as UglifyJS.

function injectedFunction(FooService, BarService) {
  // FooService and BarService are injected
}

Function annotation

A function may be annotated with an array of dependency names as the $inject property.

injectedFunction.$inject = [ 'FooService', 'BarService' ];
function injectedFunction(fs, bs) {
  // FooService and BarService are injected as fs and bs parameters
}

Array notation

An array provides the names of the dependencies to inject (as strings). The function is the last element of the array.

[ 'FooService', 'BarService', function (fs, bs) {
  // FooService and BarService are injected as fs and bs parameters
}]

This object implements four methods similar to the angular 1 promise api

UI-Router evolved from an angular 1 library to a framework agnostic library. However, some of the ui-router-core code uses these ng1 style APIs to support ng1 style dependency injection.

This API provides native ES6 promise support wrapped as a $q-like API. Internally, UI-Router uses this $q object to perform promise operations. The angular-ui-router (ui-router for angular 1) uses the $q API provided by angular.
