The component where the child route should get rendered must contain the ________ directive in its template.
To render a child route's content in an Angular component, you must include the acts as a placeholder where the child route's components will be displayed.
You're working on an application where rapid development and minimal setup are crucial. Which state management solution would you likely prefer given its simplicity?
- Angular Services
- MobX
- NgRx
- RxJS Observables
In a scenario where rapid development and minimal setup are crucial, MobX would likely be preferred due to its simplicity. MobX is a state management library that requires less boilerplate code compared to NgRx and provides a straightforward way to manage state in Angular applications.
When using Lazy Loading, which property in the Angular routing configuration is used to point to the lazily loaded module?
- importModule
- lazyModule
- loadChildren
- loadModule
When implementing Lazy Loading in Angular, the loadChildren property in the routing configuration is used to specify the path to the lazily loaded module. This allows Angular to load the module on-demand when the associated route is visited, improving initial page load times.
The @Output() decorator is used to emit custom ________ from a component.
- input events
- methods
- output events
- properties
The @Output() decorator is used to emit custom output events from an Angular component. These events allow a component to communicate with its parent or containing components. By emitting custom events, a child component can notify its parent about specific actions or changes, enabling parent-child communication in Angular applications.
Which state management solution is based on the concept of stores and queries?
- Akita
- MobX
- Redux
- RxJS
Akita is based on the concept of stores and queries. In Akita, stores hold the application state, and queries are used to retrieve and manipulate data from these stores. This pattern makes state management in Akita efficient and intuitive.
Which Angular CLI command helps in updating your Angular application to the latest version?
- ng migrate
- ng refresh
- ng update
- ng upgrade
The ng update command in Angular CLI is used to update your Angular application to the latest version of Angular and its dependencies. It helps you keep your application up-to-date with the latest features, bug fixes, and security patches.
When setting up routes in an Angular application, which property in the route configuration determines the component that should be displayed?
- component
- displayComponent
- loadChildren
- routeComponent
In Angular routing, the 'component' property in the route configuration is used to determine which component should be displayed when the route is activated. This is where you specify the component class that corresponds to the route. The 'component' property plays a fundamental role in defining the view associated with a route.
In Jasmine, what function is used to group together related test cases?
- afterEach()
- beforeAll()
- describe()
- it()
In Jasmine, the describe() function is used to group related test cases together. It provides a way to organize and structure your test suite by grouping individual test specs within a larger block. This helps in better test organization and readability.
The ng build command, by default, creates the output in the dist/______ directory.
- app
- build
- project
- your-app-name
The ng build command, by default, creates the output in the dist/ directory of your Angular project. This directory contains the production-ready build of your application that you can deploy to a web server.
In which scenario would you use the updateOn option with a value of 'blur' for a FormControl?
- To update the control only on user focus.
- To update the control only on user input.
- To update the control immediately after any change.
- To update the control on a custom event trigger.
You would use the updateOn option with a value of 'blur' for a FormControl when you want the control to update its value and trigger validation only when the user focuses on it (on blur). This can be helpful to provide a more user-friendly experience by not showing immediate validation errors as the user types. Options like 'user input' or 'immediately after any change' would lead to different behaviors not associated with 'blur.'
