Let’s level up 🔥 You're now entering FAANG+ IIT Zone™ — not just "do you know Angular", but can you master Angular like an architect?

We'll now cover:

Signals ⚡ | Standalone Components 🧩 | FormBuilder vs FormControl 🧠 | RxJS Pro 🔁 | Clean Architecture 🧱 | Monorepo and Microfrontend 💥

Each comes with:

1. FAANG-style Interview Question

2. Answer like an IIT topper

3. Code Example

---

⚡ Q9. What are Angular Signals? How are they better than traditional reactive patterns?

✅ Answer:

Signals (Angular 17+) are reactive primitives for tracking and reacting to state changes, like reactive variables.
They are better than @Input() + ChangeDetectionStrategy.OnPush because:

• No dirty checking

• Fine-grained reactivity

• Easy to debug and manage

---

🧑‍💻 Code Example:

import { signal, computed } from '@angular/core';

export class CounterComponent {
  count = signal(0);
  doubleCount = computed(() => this.count() * 2);

  increment() {
    this.count.update(v => v + 1);
  }
}

html
<!-- counter.component.html -->
<button (click)="increment()">+</button>
<p>Count: {{ count() }}</p>
<p>Double: {{ doubleCount() }}</p>

✅ No ChangeDetectorRef, no Zone.js, no headache. Instant updates.

---

🧩 Q10. What are Standalone Components and why are they revolutionary?

✅ Answer:

Angular now lets you create components without a module! These standalone components:

• Are tree-shakable

• Reduce boilerplate

• Great for MFE & SSR

---

🧑‍💻 Code Example:

ts
@Component({
  standalone: true,
  selector: 'app-hello',
  template: `<p>Hello Standalone!</p>`,
  imports: [CommonModule]
})
export class HelloComponent {}

✅ Use them directly in routes:

{ path: 'hello', component: HelloComponent }

---

🧠 Q11. FormBuilder vs FormControl vs FormGroup?

✅ Answer:

• FormControl: Individual form field (input, select)

• FormGroup: Group of FormControls

• FormBuilder: Shortcut syntax for creating FormGroup trees

---

🧑‍💻 Code Example:

ts
// Long way
form = new FormGroup({
  name: new FormControl(''),
  email: new FormControl(''),
});

// Short way
constructor(private fb: FormBuilder) {
  this.form = this.fb.group({
    name: [''],
    email: [''],
  });
}

✅ FormBuilder = Less code, more readable, preferred in large apps

---

🔁 Q12. RxJS Pro: What’s the difference between switchMap, mergeMap, and concatMap?

✅ Answer:

Operator	Behavior	Use case
switchMap	Cancels previous	Search bar typing
mergeMap	Runs in parallel	API batch calls
concatMap	Runs sequentially	Queued uploads

---

🧑‍💻 Code Example:

ts
this.search$.pipe(
  debounceTime(300),
  switchMap(query => this.api.search(query))
).subscribe(results => this.data = results);

✅ switchMap cancels older requests — fastest + cleanest.

---

🧱 Q13. What is Clean Architecture in Angular apps?

✅ Answer:

Clean Architecture in Angular means:

• Separation of concerns

• Feature-based folders

• UI, business logic, and data layers are isolated

Structure:

bash
/app
  /features
    /resume
    /chat
  /shared
    /ui
    /services
    /models

✅ Think: “Can I rip a feature out without breaking everything?”

---

💥 Q14. What is a Monorepo in Angular? How do you manage it?

✅ Answer:

A Monorepo is a single repo managing multiple Angular apps/libraries.
Use Nx or Angular CLI workspaces for:

• Shared libs

• Fast builds (via caching)

• MFE ready structure

---

🧑‍💻 Example using Nx:

bash
npx create-nx-workspace@latest angular-monorepo

Then:

bash
apps/marketing-app
libs/ui-components
libs/auth-service

✅ Scalability + Speed = Future-proofed codebase.

---

⚔️ Q15. Microfrontend (MFE) in Angular?

✅ Answer:

Microfrontends = Split UI into multiple deployable apps.
Angular supports this using Module Federation (Webpack 5+). You can:

• Run features as independent Angular apps

• Share common libs like Auth, UI

✅ It’s the Angular way to do Amazon-style frontend architecture.

---

🧑‍💻 Code (MFE host config):

ts
// webpack.config.js
ModuleFederationPlugin({
  remotes: {
    profile: 'profileApp@http://localhost:4201/remoteEntry.js'
  }
})

Use remote component in host app.

---

💥🔥 Bonus: Q16. What are Angular Signals + RxJS Combined?

✅ You can mix Signals + RxJS using toSignal() or fromSignal().

ts
const counter = signal(0);
const counter$ = toObservable(counter); // RxJS stream
const newSignal = fromObservable(counter$);

Next levels QnA in Angular/HTML/CSS/JS
Let's go full-throttle into the Next-Level Angular + HTML + CSS + JS Interview Q&A Pack — the kind of questions that separate "I follow tutorials" from "I build frameworks for fun". 🧠💻
Each question is FAANG-style, with real-world code, IIT-style clarity, and zero fluff.

⚡ SECTION 1: Angular — Beyond Basics

✅ Q1. How does ViewChild differ from ContentChild?
Answer:


ViewChild = Access DOM inside the component template


ContentChild = Access DOM projected via <ng-content>



🧑‍💻 Code Example:
ts

@ViewChild('btn') button!: ElementRef;
@ContentChild('projectedContent') projected!: ElementRef;

html

<!-- component.html -->
<button #btn>Click Me</button>
<ng-content></ng-content>

html

<!-- app.component.html -->
<custom-comp>
  <div #projectedContent>Injected</div>
</custom-comp>

✅ ViewChild is like internal camera, ContentChild is like security footage from outside.

✅ Q2. Difference between ngIf vs *ngIf?
Answer:


ngIf: Structural directive


*ngIf: Sugar syntax for <ng-template [ngIf]>



🧑‍💻 Code Simplified:
html
<!-- These are same -->
<div *ngIf="isLoggedIn">Welcome!</div>

<ng-template [ngIf]="isLoggedIn">
  <div>Welcome!</div>
</ng-template>

✅ *ngIf rewrites the DOM — that’s why it’s called structural directive.

✅ Q3. Explain Angular Lifecycle Hooks with a Real Flow
Answer:

Common hooks:


ngOnInit() → after input is set


ngAfterViewInit() → after view/template is rendered


ngOnDestroy() → before component is destroyed



🧑‍💻 Code Flow:
ts
export class DemoComponent implements OnInit, AfterViewInit, OnDestroy {
  ngOnInit() { console.log('Init'); }
  ngAfterViewInit() { console.log('View Ready'); }
  ngOnDestroy() { console.log('Destroyed'); }
}

✅ Use case: Clean up subscriptions in ngOnDestroy.

🧩 SECTION 2: HTML — Real World Questions

✅ Q4. What is the difference between <section>, <div>, and <article>?
Answer:
Tag
Meaning
Use Case
<div>
Generic block
Layout container
<section>
Thematic group
Group of content
<article>
Self-contained
Blog, post, comment

🧑‍💻 Code Example:
html
<article>
  <h2>Blog Post</h2>
  <p>This is an article.</p>
</article>

<section>
  <h3>Related Articles</h3>
</section>

✅ Use semantic tags for accessibility + SEO boost.

✅ Q5. What is aria-*? Why is it important?
Answer:

aria-* attributes help with Accessibility (A11y) for screen readers, navigation, etc.

🧑‍💻 Code Example:
html
<button aria-label="Close modal" (click)="close()">X</button>

✅ Accessibility = bonus points in interviews and real life.

🎨 SECTION 3: CSS — Modern Styling & Tricks

✅ Q6. What is the difference between rem, em, and %?
Answer:
Unit
Based On
Use
em
Parent font size
Relative inside container
rem
Root font size (html)
Consistent scaling
%
Relative to parent
Use in width/height/layout

🧑‍💻 Code Example:
css
html { font-size: 16px; }
p { font-size: 2rem; } /* = 32px */

✅ Use rem for predictable sizing, em for nested scaling.

✅ Q7. How does Flexbox differ from Grid?
Answer:
Feature
Flexbox
Grid
Axis
One-dimensional
Two-dimensional
Use case
Layout rows/columns
Complex layouts

🧑‍💻 Code Snippet:
css
/* Flex */
.container {
  display: flex;
  justify-content: space-between;
}

/* Grid */
.grid {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
}

✅ Use Grid for layout, Flexbox for alignment.

🔥 SECTION 4: JavaScript — DOM + Data + Logic

✅ Q8. What’s the difference between == vs ===?
Answer:


==: Loose equality (performs type coercion)


===: Strict equality (no coercion)


js
'1' == 1    // true
'1' === 1   // false

✅ Always prefer === to avoid surprises.

✅ Q9. What is Event Delegation in JS?
Answer:

Event Delegation = Put listener on parent, capture events from children.

Great for performance and dynamic DOM.

🧑‍💻 Code Example:
js
document.getElementById('list').addEventListener('click', (e) => {
  if (e.target.tagName === 'LI') {
    alert(`Clicked: ${e.target.textContent}`);
  }
});

✅ One listener for 100+ items. Clean and fast.

✅ Q10. What is a Closure? Real example?
Answer:

Closure = A function remembers variables from its lexical scope, even after outer function is done.

🧑‍💻 Code Example:
js

function counter() {
  let count = 0;
  return () => ++count;
}

const inc = counter();
console.log(inc()); // 1
console.log(inc()); // 2

✅ Closures are used in React hooks, debouncing, and RxJS.

Alright champ 👑 — welcome to your Mock Interview: Angular + JavaScript (FAANG Edition) 🎯

You're in the hot seat now.

I'll hit you with 10 real-world, high-signal interview questions — you answer first (if you want), and I’ll follow each with the perfect solution + code.

🚀 MOCK INTERVIEW STARTS NOW

🔥 Q1: Angular - What is the difference between @Input() and @Output()? When would you use them?
✅ Answer:


@Input() → Pass data from parent to child


@Output() → Emit events from child to parent



🧑‍💻 Code Example:
ts

// child.component.ts
@Input() name: string = '';
@Output() greet = new EventEmitter<string>();

sayHi() {
  this.greet.emit(`Hello, ${this.name}`);
}

html
<!-- parent.component.html -->
<app-child [name]="'Raj'" (greet)="onGreet($event)"></app-child>

ts

onGreet(msg: string) {
  console.log(msg); // Hello, Raj
}

✅ Use @Input to receive, @Output to communicate back.

⚡ Q2: JavaScript - What is hoisting? Give an example.
✅ Answer:
Hoisting is when variable and function declarations are moved to the top of the scope before execution.

🧑‍💻 Code Example:
js

console.log(a); // undefined
var a = 5;

sayHi(); // "Hi"
function sayHi() {
  console.log("Hi");
}

✅ Only var and function declarations are hoisted — not let, const, or function expressions.

🧠 Q3: Angular - Explain RxJS with a real use case like search autocomplete.
✅ Answer:
Use debounceTime and switchMap to avoid firing API calls on every keystroke.

🧑‍💻 Code:
ts

search$ = new Subject<string>();

ngOnInit() {
  this.search$
    .pipe(
      debounceTime(300),
      switchMap(query => this.api.search(query))
    )
    .subscribe(result => console.log(result));
}

onSearch(query: string) {
  this.search$.next(query);
}

✅ debounceTime = smooth UX, switchMap = cancel old calls.

🧩 Q4: JavaScript - What’s the difference between == and ===?
✅ Answer:


== → compares value, does type coercion


=== → compares value and type


js

'5' == 5     // true
'5' === 5    // false

✅ Use === always to avoid JS traps.

🎯 Q5: Angular - What is ngOnChanges() and when does it trigger?
✅ Answer:
ngOnChanges() is a lifecycle hook that runs whenever an @Input() value changes.

🧑‍💻 Code:
ts

@Input() counter: number = 0;

ngOnChanges(changes: SimpleChanges) {
  console.log('Counter changed', changes.counter);
}

✅ Great for reacting to parent updates in child components.

💥 Q6: JavaScript - What is a closure? Use in counter function?
✅ Answer:
A closure is when a function remembers variables from its outer scope.

🧑‍💻 Code:
js

function createCounter() {
  let count = 0;
  return function () {
    return ++count;
  };
}

const counter = createCounter();
console.log(counter()); // 1
console.log(counter()); // 2

✅ Used in React hooks, caching, debounce, Angular services.

🧠 Q7: Angular - Explain Change Detection and ChangeDetectionStrategy.OnPush
✅ Answer:
Angular checks if anything changed and re-renders.

With OnPush, it only re-renders on:


New @Input() value


Observable emits


User event



🧑‍💻 Code:
ts

@Component({
  selector: 'app-smart',
  template: `{{ value }}`,
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class SmartComponent {
  @Input() value: string = '';
}

✅ Massive performance boost in large apps.

🎨 Q8: JavaScript - What are Promises and Async/Await?
✅ Answer:


Promise = object for async result


Async/Await = syntactic sugar over Promises



🧑‍💻 Code:
js
function fetchData() {
  return new Promise(resolve => {
    setTimeout(() => resolve('Data loaded'), 1000);
  });
}

async function getData() {
  const result = await fetchData();
  console.log(result); // Data loaded
}

✅ Cleaner async logic, readable as sync.

🧱 Q9: Angular - What is Lazy Loading? Show routing example.
✅ Answer:
Lazy loading loads modules only when needed, reducing initial bundle size.

🧑‍💻 Code:
ts
// app-routing.module.ts
const routes: Routes = [
  {
    path: 'admin',
    loadChildren: () =>
      import('./admin/admin.module').then(m => m.AdminModule)
  }
];

✅ Crucial for scalable enterprise Angular apps.

🚀 Q10: JavaScript - Explain this keyword with arrow vs normal functions.
✅ Answer:


In arrow function: this is lexically scoped (inherits from parent)


In regular function: this is dynamic (depends on call context)



🧑‍💻 Code:
js
const obj = {
  name: 'Raj',
  arrow: () => console.log(this.name),      // undefined
  normal() { console.log(this.name); }      // Raj
};

obj.arrow();   // ❌
obj.normal();  // ✅

✅ Arrow functions are bad for object methods that depend on this.
