Angular Sample Question 1:

What is the difference between ngIf and ngShow/ngHide directives in Angular?

  • Option 1: The ngFor directive is used to handle user events in Angular.
  • Option 2: The ngFor directive is used for styling HTML elements in Angular.
  • Option 3: The ngFor directive is used to bind data to a template and repeat HTML elements based on an iterable.
  • Option 4: The ngFor directive is used to declare dependencies in Angular.

Correct Answer: Option 3


The ngFor directive in Angular is used to iterate over a collection and generate HTML elements dynamically. It takes an iterable (such as an array) and repeats a portion of HTML code for each item in the collection. Within the ngFor loop, you can access properties and methods of the current item using a local variable. The ngFor directive is commonly used to display lists, tables, or any other repeating elements in Angular templates.

Angular Sample Question 2:

What is an observable in Angular and how is it used?

  • Option 1: An observable in Angular is a mechanism used to manage server-side logic.
  • Option 2: An observable in Angular is a class used to style HTML elements.
  • Option 3: An observable in Angular is a component used to handle user events.
  • Option 4: An observable in Angular is an asynchronous data stream that can be observed and processed using operators.

Correct Answer: Option 4


In Angular, an observable is a powerful data handling mechanism based on the Reactive Programming paradigm. It represents an asynchronous data stream that can emit multiple values over time. Observables are used extensively in Angular for handling asynchronous operations such as making HTTP requests, handling user events, or managing data streams. Observables can be combined, transformed, filtered, and subscribed to using operators, allowing for efficient data manipulation and handling. They provide a convenient way to handle asynchronous operations, manage data streams, and react to changes in the application.
