💡 Self-Explanatory Overview: In simple, everyday terms, Angular DI Hierarchy, Change Detection Internals & Senior Frontend Interviews teaches you how Angular applications explain OnPush vs Signals, memory-leak-free takeUntilDestroyed(), and monorepo architecture. Even if you have never seen this concept before, your trainer explains the real-life problem first, writes clean Angular (Ivy AOT & Standalone APIs), Fine-Grained Angular Signals, TypeScript 5 Strict Mode code live on screen, and shows what breaks in production if this step is skipped.
🎯 For What Purpose: To understand and apply Angular DI Hierarchy, Change Detection Internals & Senior Frontend Interviews in real Angular systems — specifically: Explain OnPush vs Signals, memory-leak-free takeUntilDestroyed(), and monorepo architecture, so your code stays reliable, fast, and easy to maintain in production.
