In a Route Guard, to navigate to a different route due to an authorization failure, you would typically use the router.______ method.
- forwardTo
- handleError
- navigate
- redirectTo
In a Route Guard, to navigate to a different route due to an authorization failure, you would typically use the router.navigate method. This allows you to redirect the user to a different route when authorization fails or when specific conditions are not met.
Your application's components have styles that are unexpectedly affecting other unrelated components. How would you ensure that component styles are isolated and don't interfere with other parts of the application?
- Use ViewEncapsulation.Emulated in component metadata
- Use global stylesheets for component-specific styles
- Apply unique CSS classes to each component and prefix all CSS selectors with these classes
- Set the CSS 'all' property to 'initial' for the component's root element
To ensure that component styles are isolated and don't interfere with other parts of the application, you would use ViewEncapsulation.Emulated in the component's metadata. This encapsulation mode creates unique CSS selectors for each component, preventing unintended style inheritance. The other options may not provide the same level of style isolation and control.
The process of splitting an Angular application into multiple bundles, where each bundle is loaded lazily on demand, is known as ________.
- Ahead-of-Time Compilation
- Code Splitting
- Lazy Loading
- Tree Shaking
The process of splitting an Angular application into multiple bundles, where each bundle is loaded lazily on demand as needed, is known as "Lazy Loading." This technique helps improve application performance by loading only the necessary code chunks when navigating to different parts of the application.
Akita promotes the idea of separating UI state from ________ state.
- Entity
- Feature
- Local
- Shared
Akita encourages the separation of UI state from Entity state. Entity state typically represents data structures and business logic, while UI state deals with presentation-specific concerns. Separating them helps in better code organization and maintainability.
How do you set default values for controls in a reactive form?
- Default values cannot be set in reactive forms.
- Use the default property of the FormControl.
- Use the setValue method of the FormControl.
- Use the value property of the FormControl.
In reactive forms, you set default values for controls by using the value property of the FormControl object. This property allows you to specify the initial value of the control. You can also use the setValue method to set the value programmatically after the control has been created. The default property is not used for setting default values in reactive forms.
In Angular, the _____ decorator is used to bind a property in the child component to receive a value from the parent component.
- @ContentChild
- @Input
- @Output
- @ViewChild
In Angular, the @Input decorator is used to bind a property in the child component, allowing it to receive a value from the parent component. This is commonly used for passing data from a parent to a child component.
When using multi-slot content projection, the content that doesn't match any selector will be projected into the without a select ________.
- Default
- Placeholder
- Slot
- Tag
In Angular, when you use multi-slot content projection, any content that doesn't match any selector will be projected into the element without a select attribute. This is often referred to as the "default" slot, and it's where unmatched content is placed. Options 2, 3, and 4 are not the standard terms used for this behavior.
In NgRx, what is responsible for specifying how state changes in response to actions?
- Actions
- Effects
- Reducers
- Selectors
In NgRx, reducers are responsible for specifying how the state changes in response to actions. Reducers are pure functions that take the current state and an action as arguments and return a new state. They define how the application's state should be updated based on dispatched actions.
Structural directives manipulate the ________ by adding, removing, or replacing elements.
- Angular component structure
- CSS stylesheet structure
- DOM structure
- HTML attributes structure
Structural directives in Angular manipulate the DOM structure by adding, removing, or replacing elements within the DOM. They are a core feature of Angular's template syntax and are used to conditionally render or modify parts of the DOM based on application logic. Understanding how structural directives work is essential for creating dynamic and responsive Angular applications.
What is the primary difference between single-slot and multi-slot content projection?
- Single-slot projects content into a single container, while multi-slot can project content into multiple containers.
- Single-slot requires custom structural directives, while multi-slot uses built-in Angular directives.
- Single-slot is used for simple components, while multi-slot is for complex components.
- Single-slot allows for one-way data binding, while multi-slot enables two-way data binding.
The primary difference between single-slot and multi-slot content projection in Angular is that single-slot projects content into a single container within the component's template, while multi-slot can project content into multiple predefined containers. This allows for more fine-grained control over where different parts of content are placed within the component. The other options do not accurately describe the difference between these two projection methods.
