Understanding how DI works at different levels (Module, Component, Environment) allows you to explain singleton services versus component-scoped services, crucial for architecture questions. How to Prepare Using the "Hacking" Method

State management scaling laws (when local Signals are enough versus when to introduce Akita, NgRx, or SignalStore).

import signal, computed, effect from '@angular/core'; // 1. Defining a writable signal const quantity = signal(1); // 2. Defining a computed signal (automatically tracks dependencies) const price = signal(10); const totalCost = computed(() => quantity() * price()); // 3. Updating a signal value quantity.set(5); // Direct overwrite quantity.update(q => q + 1); // Update based on previous value // 4. Effects for side-effects (e.g., logging or local storage sync) effect(() => console.log(`The updated total cost is: $totalCost()`); ); Use code with caution. 3. RxJS Architectural Patterns
