Laravel routing allows you to define application routes in the `routes/web.php` file using a simple and expressive syntax, enabling you to manage application URLs and their corresponding actions easily.
6) What is Blade templating in Laravel?
Blade is Laravel's native templating engine that allows you to create dynamic HTML templates using a simple syntax, making it easy to include and extend templates with features like template inheritance.
7) What is a Service Provider in Laravel?
A Service Provider is a central place to configure and bootstrap the various components of a Laravel application, allowing you to register services, bind classes to the service container, and perform other initialization tasks.
8) Explain the purpose of the .env file in Laravel.
The .env file is used to manage environment specific configuration settings for a Laravel application, such as database connection credentials, enabling easy changes without altering the source code.
9) How does Laravel implement migrations?
Laravel migrations provide a version control system for your database schema, allowing you to create and modify tables and columns programmatically using PHP code, which can be easily shared across environments.
10) What is API Resource in Laravel?
API Resources in Laravel provide a way to transform models into JSON format, allowing easy construction of custom responses for API endpoints while ensuring consistency in output.
11 - What are Jobs and Queues in Laravel?
