How does AngularJS handle large-scale frontend system design trade-offs?

AngularJS system design involves trade-offs between performance, maintainability, and flexibility.

Designing AngularJS systems at scale requires balancing conflicting goals. Two-way binding improves developer speed but reduces performance. Event-driven architecture improves decoupling but increases complexity. Service abstraction improves maintainability but adds indirection. Architects must choose patterns based on business priorities and performance budgets.
