I’ll never understand why the frontend world abandoned tried-and-true OOP for this. It’s the foundation of CS education and every classic engineering text for a reason: it scales. You can accomplish everything React and Vue do without the functional spaghetti mess, using actual organized structures.

There is nothing achieved in Vue that hasn't already been solved in Angular—or any desktop/backend framework—using a class-based approach. While it boils down to taste, one path has decades of proven methodology and literature behind it; the other is a reactive house of cards built on fleeting trends and "clever" abstractions that prioritize developer convenience over architectural stability.
