Angularjs Dependency Injection notation

The following two types of dependency injection are equivalent:

"The First Kind"

function (Notifier, Private, Timefilter, config) {  //  const Notifier = $injector. Get (' Notifier ');  //  Const PRIVATE = $injector. Get (' Private ');  // Const Timefilter = $injector. Get (' Timefilter ');  // Const CONFIG = $injector. Get (' config ');  // ... other codes

"The second Kind"

function ($injector) {   = $injector. Get (' Notifier ');    = $injector. Get (' Private ');    = $injector. Get (' Timefilter ');    = $injector. Get (' config ');   // ... other codes
