Explain directives in Angular. Can you name a few types?
Directives: Directives are used to manipulate the DOM, modify the appearance, behavior, or functionality of elements, and enhance the overall user experience.
Examples: Examples of directives in Angular include ngFor, ngIf, ngClass, ngStyle, and ngModel.
NgFor: The ngFor directive is used for repeating elements in a template by iterating over a collection.
Iterable: It takes an iterable (such as an array or object) and generates a template instance for each item.
Dynamically Render :This allows developers to dynamically render content based on data.
NgIf Directive: The ngIf directive is used for conditionally rendering elements based on a boolean expression.
Evaluates Expression: It evaluates the expression and determines whether to show or hide the associated content.
User Interactions: This enables developers to dynamically change the visibility of elements based on data or user interactions.
NgClass Directive :The ngClass directive is used for dynamically adding or removing CSS classes to elements.
Conditional: It allows developers to apply different styles based on certain conditions or state changes.
Flexibility: This provides flexibility in styling elements based on data or user interactions.
NgStyle Directive: The ngStyle directive is used for dynamically applying inline CSS styles to elements.
Change Appearance : It allows developers to change the appearance or layout of elements based on specific conditions or user interactions.
Dynamic and Responsive: This enables the creation of dynamic and responsive user interfaces.
NgModel Directive: The ngModel directive is used for two-way data binding between input elements and component properties.
Synchronize: It provides a convenient way to synchronize values entered by users with the underlying data model.
Real-Time Updates: This facilitates real-time updates and ensures a consistent state between the user interface and application data.
