A Few Practical Notes on OOP

Points Worth Knowing

• Encapsulation hides a class's internal details, letting its implementation change without affecting the rest of the program.
• Polymorphism lets different classes share common behavior through a shared interface, while each implements it differently.
• OOP is extremely common in languages like PHP, Java, and Python, but it's far from the only programming paradigm out there.

Takeaway

None of these points are complicated on their own, but knowing them can lead to better technical decisions about OOP on your next project.
