A specific instance of a class containing real values instead of placeholders.
Mastering OOP allows you to truly understand what happens under the hood of the Laravel framework. The Service Container

: Organizing code hierarchy and shared behaviors.
A User parent class can be extended into Admin and Customer child classes, sharing base logic while allowing unique features for each role. 3. Polymorphism
The code you download is a starting line, not a finish line. Use these object-oriented principles to build Laravel applications that are maintainable, testable, and a joy to work on—long after the tutorial ends.
