Laravel - Action URL

Laravel 5.7 introduces a new feature called “callable action URL”. This feature is similar to the one in Laravel 5.6 which accepts string in action method. The main purpose of the new syntax introduced Laravel 5.7 is to directly enable you access the controller.
The syntax used in Laravel 5.6 version is as shown −

< ?php
$url = action('UserController@profile', ['id' => 1]);

The similar action called in Laravel 5.7 is mentioned below −

< ?php
$url = action([PostsController::class, 'index']);

One advantage with the new callable array syntax format is the feature of ability to navigate to the controller directly if a developer uses a text editor or IDE that supports code navigation.
