Data Binding and Templates
Data binding connects application logic with the user interface. Angular provides multiple ways to bind data one way event based and two way binding.
For example developers can display data dynamically listen to user interactions and automatically update the view when variables change. The concept of binding is one of the most commonly tested areas in Angular MCQ Questions.
Components and Their Functionality
Components and Their Functionality define the building blocks of an Angular application each controlling a specific part of the user interface.They help organize the app into smaller reusable pieces making development faster and easier to manage.
Role of Components
Components form the building blocks of every Angular application. Each component controls a specific section of the user interface and encapsulates logic related to that section.
A component typically defines three main parts:
- The class that handles logic and data
- The HTML template that defines the view
- The styles that apply design to the template
Angular MCQ Questions often assess understanding of how components are declared structured and connected within modules.
Lifecycle Hooks
Lifecycle hooks are special methods that allow developers to control a component’s behavior during its creation update and destruction. Common hooks include initialization content loading view rendering and cleanup.
For instance ngOnInit runs after the component’s data-bound properties are initialized while ngOnDestroy is executed before the component is removed from the DOM.
Knowing when these lifecycle events occur is essential for debugging and optimization a frequent theme in Angular MCQ Questions.
Communication Between Components
Angular supports communication between components through @Input() and @Output() decorators. These decorators facilitate data exchange between parent and child components ensuring a structured data flow.
Many Angular MCQ Questions assess your understanding of how data flows between components as it’s a cornerstone concept in application design.
Directives and Pipes
Directives and Pipes in Angular are powerful features that help you control how elements behave and how data is displayed in your application.
They make your code cleaner more dynamic and easier to manage while enhancing the overall user experience.
What Are Directives?
Directives extend the capabilities of HTML elements by adding custom behavior or altering their appearance. Angular provides two main types of directives structural and attribute.
- Structural Directives modify the layout by adding or removing elements dynamically.
- Attribute Directives alter the appearance or behavior of elements without changing the DOM structure.
Knowing which directive to use and how it impacts the DOM is a frequent point of focus in Angular MCQ Questions.
Understanding Pipes
Pipes are used to transform data in templates. They format data into a more readable form such as converting text to uppercase formatting numbers or adjusting date values.
Angular includes several built in pipes but developers can also create custom pipes for specific transformations. The process of implementing custom pipes and their use cases is a common area in Angular MCQ Questions.
Routing and Navigation in Angular
Routing and Navigation in Angular allow users to move between different views or components seamlessly within a single page application.It helps create a smooth user experience by managing URLs and linking various parts of the app efficiently.
Routing Basics
Routing enables Angular applications to transition between different views or components without reloading the page. It defines how users navigate through various parts of the app using URLs.
Each route links to a specific component making Angular applications highly responsive and interactive. Angular MCQ Questions often include queries about route configuration navigation methods and default paths.
Route Guards and Wildcards
Route guards control access to routes ensuring that users only access authorized sections of an application. This feature is often implemented through interfaces that check authentication status before loading a route.
A wildcard route often represented by a double asterisk catches undefined paths and redirects users to a fallback view another important concept tested in Angular MCQ Questions.
Lazy Loading Modules
Lazy loading is a performance optimization technique where modules are loaded only when needed. It prevents unnecessary code from being loaded during initial startup significantly improving application performance.
Understanding the benefits and configuration of lazy loading is vital for developers preparing for advanced Angular MCQ Questions.
Forms in Angular Applications
Forms in Angular Applications are used to collect validate and manage user input efficiently. They make it easy to create interactive dynamic and data driven web pages with smooth user experiences.
Template Driven and Reactive Forms
Angular provides two main approaches for handling forms template driven and reactive forms. Template driven forms are simple to implement and suitable for basic use cases while reactive forms offer better control and scalability for complex applications.
Reactive forms are built using form models in TypeScript allowing for advanced validation condition handling and dynamic form creation. Knowing the differences between these two types of forms is critical when practicing Angular MCQ Questions.
Form Validation
Angular’s form module offers built in validators that ensure user input is accurate and meets specific criteria. Developers can also create custom validators for more specialized checks.
Form validation enhances user experience by preventing submission of invalid data. Since validation logic forms the backbone of interactive web applications related Angular MCQ Questions are extremely common.
Dependency Injection and Services
Dependency Injection and Services in Angular allow you to share data logic and functionality across different components efficiently.They make your code more modular reusable and easier to maintain throughout your application.
Concept of Dependency Injection
Dependency Injection DI is one of Angular’s core principles. It allows components to receive instances of required services automatically promoting modularity and reusability.
Angular’s injector system creates and delivers instances of dependencies when needed avoiding manual instantiation and improving testability. Understanding how DI works is crucial as it frequently appears in Angular MCQ Questions.
Services in Angular
Services contain business logic that can be reused across multiple components. They are defined as classes and provided at the root or module level depending on the scope.
When preparing for Angular MCQ Questions it’s important to understand how services are created provided and injected as this determines the behavior and reusability of the codebase.
Observables and RxJS Integration
Observables and RxJS Integration allow Angular applications to handle asynchronous data streams efficiently and reactively.
