Can you explain the basic concept of MVC architecture in Laravel?
Model Answer
A strong candidate would describe the MVC (Model-View-Controller) architecture as a pattern that separates the application into three main logical components. The Model handles data logic, the View handles the UI logic, and the Controller processes incoming requests, retrieves data from the Model, and passes it to the View.
Example
For instance, in a blog application, the Model would manage the blog data, the View would present the articles, and the Controller would handle user requests for viewing posts.
