Why do design patterns matter in Angular development?

They help organize code, make it easier to understand, maintain, and scale. Patterns also promote best practices and reduce bugs.

How do design patterns improve teamwork in software projects?

They provide a common language and structure, so team members understand each other's code better and work together smoothly.

Give an example of a design pattern commonly used in Angular.

The Singleton pattern is common in Angular services to ensure only one instance manages shared data or logic.

How do design patterns help when maintaining or updating an Angular app?

They make the code predictable and modular, so changes can be made safely without breaking other parts.

What is the main benefit of using design patterns in Angular?

A They make code easier to read and maintain

B They increase app size

C They slow down development

D They remove the need for testing

Design patterns help organize code, making it easier to read and maintain.

Which design pattern ensures only one instance of a service exists in Angular?

A Factory

B Singleton

C Observer

D Decorator

Singleton pattern ensures a single instance of a service is used throughout the app.

How do design patterns help teams working on the same Angular project?

A By providing a common structure and language

B By making code unpredictable

C By hiding code from teammates

D By forcing everyone to write code the same way

Design patterns provide a shared structure and language that improves team communication.

Which of these is NOT a reason design patterns matter?

A They improve code readability

B They make code modular

C They reduce bugs

D They guarantee no bugs

Design patterns help reduce bugs but do not guarantee code is bug-free.

When updating an Angular app, design patterns help by:

A Automatically fixing errors

B Making code harder to change

C Making code modular and predictable

D Removing the need for documentation

Patterns make code modular and predictable, easing updates and maintenance.
