Attribute Directives – Change appearance/behavior (e.g., ngClass, ngStyle)?

Examples:

<!-- *ngIf -->

<div *ngIf="user.isLoggedIn">Welcome, {{ user.name }}</div>

<!-- *ngFor -->

<li *ngFor="let item of items">{{ item }}</li>

Real-Time Example:

In a to-do app, *ngFor is used to loop through tasks and display them.
