You are optimizing an Angular application and want to ensure that the generated code is as small as possible for faster load times. How can the Ivy Renderer assist in achieving this goal?
- Better component encapsulation
- Enhanced routing performance
- Faster compilation
- Improved tree-shakability
The Ivy Renderer assists in generating smaller code by improving tree-shakability. Tree shaking eliminates unused code during the build process, resulting in a smaller bundle size for faster loading times.
You are tasked with implementing a sign-up form where the password field must match the confirm password field. Which approach would you use to validate this in Angular?
- Built-in Validators
- Custom Validator Function
- Service-based Validation
- Two-way data binding with ngModel
To validate that the password and confirm password fields match, you should use a Custom Validator Function in Angular to implement custom validation logic.
What is the impact of lazy loading on the initial load time of an Angular application?
- It depends on the module
- It has no impact
- It increases initial load
- It reduces initial load
Lazy loading has a positive impact on the initial load time of an Angular application as it reduces the initial load by loading modules on-demand.
Which RxJS operator can be used to combine multiple Observables into a single Observable?
- concat
- filter
- merge
- pluck
The merge operator in RxJS is used to combine multiple Observables into a single Observable, emitting values from all source Observables concurrently.
Angular Elements encapsulates the complexity of Angular's _____, making it more approachable for different setups.
- Application Logic
- Component Tree
- Core Modules
- Dependency Injection
Angular Elements encapsulates the complexity of Angular's Dependency Injection, making it more approachable for different setups and simplifying the integration of Angular components into non-Angular applications.
In Angular, what is the primary purpose of a component's class?
- Define component behavior
- Define routing
- Handle user input
- Store metadata
The primary purpose of a component's class in Angular is to define component behavior, including properties, methods, and event handlers.
You're building an e-commerce application and want to create a nested navigation structure where product categories have sub-categories. How would you design the routing for this scenario using child routes?
- Configure named outlets for sub-categories
- Define child routes within the parent component
- Implement a shared module for navigation
- Use auxiliary outlets for sub-categories
To create nested navigation with sub-categories, you should define child routes within the parent component. This allows for a hierarchical structure in your routing.
What is the purpose of a Form Group in Angular Reactive Forms?
- Define form submission actions
- Define form validation rules
- Group related form controls
- Store form control values
The purpose of a Form Group in Angular Reactive Forms is to group related form controls together. It helps manage and validate a set of related form controls.
Angular Universal generates _____ pages to improve the initial load time of an application.
- Client-side
- Dynamic
- Server-side
- Static
Angular Universal generates server-side pages to improve the initial load time of an application.
When using Dependency Injection in Angular, what is the significance of the @Injectable() decorator?
- It creates a new instance of the service
- It handles routing in Angular
- It injects a service into a component
- It marks a service as singleton
The @Injectable() decorator is used to mark a service as a singleton, meaning that Angular will create a single instance of the service and share it across components that request it.
