Q3: What are AngularJS templates?

A3: AngularJS templates are HTML files with additional AngularJS-specific syntax. They define the view of an AngularJS component or directive, including data binding, directives, and event bindings.

Q4: How do you use data binding in AngularJS templates?

A4: Data binding in AngularJS templates can be achieved using interpolation (`{{ }}`), property binding (`[property]="expression"`), event binding (`(event)="handler()"`), and two-way binding (`[(ngModel)]`). This connects component data to the HTML template.

Q5: What are AngularJS directives in templates?

A5: AngularJS directives in templates are special markers in the HTML that tell AngularJS to do something to a DOM element. They can be attributes, elements, CSS classes, or comments that AngularJS interprets and transforms.

Q6: How do you handle events in AngularJS templates?

A6: Events in AngularJS templates are handled using event binding (`(event)="handler()"`). This allows you to respond to user interactions like clicks, keystrokes, or mouse movements within the template.

Q7: What is AngularJS interpolation?

A7: AngularJS interpolation (`{{ }}`) is a way to bind expressions in the view template to data in the component. It evaluates the expression and converts it to a string, displaying the result in the HTML.

Q8: How do you use ngFor and ngIf in AngularJS templates?

A8: `ngFor` is used for displaying a list of items by iterating over an array, and `ngIf` is used for conditionally rendering elements based on an expression. They are structural directives in AngularJS templates.

Q9: What is AngularJS content projection?

A9: AngularJS content projection (using ``) allows passing content into components from the outside. It enables creating flexible and reusable components that can display different content based on usage.

Q10: How do you style AngularJS components?

A10: AngularJS components can be styled using CSS, CSS preprocessors like Sass or Less, or by encapsulating styles within component-specific stylesheets using component-specific CSS encapsulation mechanisms.

Q1: How do you create forms in AngularJS?

A1: Forms in AngularJS are created using the `form ` element with AngularJS directives like `ngForm`, `ngModel`, and form control directives (`ngModel`, `ngModelGroup`). They allow for capturing and validating user input.

Q2: What is two-way data binding in AngularJS forms?

A2: Two-way data binding in AngularJS forms synchronizes data between the model (component class) and the view (HTML form elements). Changes in the model update the view, and user input in the view updates the model automatically.

Q3: How do you perform form validation in AngularJS?

A3: Form validation in AngularJS is performed using built-in validators (`required`, `minLength`, `maxLength`, `pattern`) and custom validators. Validation errors are displayed in the template using AngularJS directives and error messages.

Q4: What are AngularJS reactive forms?

A4: AngularJS reactive forms are a model-driven approach to handling form input validation and data synchronization. They are built around `FormControl`, `FormGroup`, and `FormBuilder` classes, offering more control and flexibility than template-driven forms.

Q5: How do you handle form submission in AngularJS?

A5: Form submission in AngularJS is handled using event binding (`(submit)="onSubmit()"`) on the `

` element. It triggers a method in the component class that processes the form data, performs validation, and submits it to the server if valid.

Q6: What is AngularJS form validation using ngMessages?

A6: AngularJS form validation using `ngMessages` is a directive that allows displaying error messages based on form validation states (`$error`, `$dirty`, `$pristine`, `$touched`, `$untouched`). It provides a way to show custom error messages for specific validation conditions.

Q7: How do you reset a form in AngularJS?

A7: AngularJS forms can be reset using the `reset()` method on the form control (`ngForm`) or by resetting the form model in the component class. This clears user input and resets form validation states.

Q8: How do you disable form controls in AngularJS?

A8: Form controls in AngularJS can be disabled using the `disabled` attribute binding (`[disabled]="condition"`). This prevents user interaction with the form control and visually indicates its disabled state.

Q9: What are cross-field validations in AngularJS forms?

A9: Cross-field validations in AngularJS forms involve validating multiple form fields together. This can be achieved using custom validators that compare values of multiple form controls and display validation errors accordingly.

Q10: How do you handle asynchronous validation in AngularJS forms?

A10: Asynchronous validation in AngularJS forms involves validating form input against a server or an external service. This is done using async validators (`AsyncValidatorFn`) and updating validation status based on asynchronous responses.

Q1: What is dependency injection (DI) in AngularJS?

A1: Dependency injection in AngularJS is a design pattern where a class (service or component) receives its dependencies from an external source (typically the AngularJS injector) rather than creating them itself. It promotes modularity and testability.

Q2: How does dependency injection work in AngularJS?

A2: Dependency injection in AngularJS works by defining providers (`@Injectable()` services or components) and injecting them into other components or services via constructor parameters or AngularJS injector methods (`get()`, `resolve()`).

Q3: What are AngularJS services?

A3: AngularJS services are singleton objects or functions used for carrying out specific tasks such as data fetching, authentication, logging, etc. They are shared across the application and can have dependencies injected into them.

Q4: How do you create a service in AngularJS?

A4: Services in AngularJS are created using the `@Injectable()` decorator in TypeScript, or as ES5/ES6 classes in JavaScript. They can include methods to perform specific tasks and can be injected into components or other services.

Q5: What is a provider in AngularJS?

A5: A provider in AngularJS is a recipe for creating a service instance. It can be configured with dependencies and options, and registered with the AngularJS injector to make it available for dependency injection throughout the application.

Q6: How do you handle data sharing between components in AngularJS?

A6: Data sharing between components in AngularJS can be achieved using services (which act as a centralized data store), input/output bindings (`@Input()` and `@Output()` decorators), and observables or subjects for reactive data updates.

Q7: What are the benefits of using dependency injection in AngularJS?

A7: Benefits of using dependency injection in AngularJS include modularity, testability, reusability, easier maintenance, and separation of concerns. It promotes a more structured and scalable application architecture.

Q8: How do you inject services into components in AngularJS?

A8: Services are injected into components in AngularJS using constructor injection. You declare a private or public property in the component class with the service type, and AngularJS automatically provides an instance of the service when creating the component.

Q9: What is AngularJS hierarchical dependency injection?

A9: AngularJS hierarchical dependency injection is a design pattern where services and other dependencies are injected into components based on their hierarchical relationship in the component tree. It allows sharing data across parent-child components and their descendants.

Q10: How do you provide services in AngularJS?

A10: Services in AngularJS are provided using the `@Injectable()` decorator or as classes in TypeScript. They can be registered with the AngularJS injector using the `providers` array in the module (`NgModule`) or the `@Injectable()` decorator itself.

Q1: What are AngularJS directives?

A1: AngularJS directives are markers on a DOM element (like attributes, element names, CSS classes, or comments) that tell AngularJS's HTML compiler (`$compile`) to attach a specified behavior to that DOM element or even transform the DOM element and its children.

Q2: How do you create custom directives in AngularJS?

A2: Custom directives in AngularJS are created using the `directive` function or `@Directive` decorator in TypeScript. They can modify the DOM, attach behaviors, or encapsulate reusable UI components, extending HTML with new features.

Q3: What are built-in AngularJS directives?

A3: Built-in AngularJS directives include `ngModel`, `ngIf`, `ngFor`, `ngSwitch`, `ngClass`, `ngStyle`, `ngSubmit`, `ngShow`, `ngHide`, `ngClick`, and more. They provide a way to manipulate the DOM, apply conditional logic, loop over collections, and handle user events within templates.

Q4: How do you pass data to directives in AngularJS?

A4: Data can be passed to directives in AngularJS using inputs (`@Input()` decorator) or attribute bindings. These allow components to communicate and share data, either as simple values or complex objects, enhancing the flexibility and reusability of components.

Q5: What are structural directives in AngularJS?

A5: Structural directives in AngularJS are responsible for HTML layout by adding or removing elements from the DOM based on conditions. Examples include `ngIf`, `ngFor`, and `ngSwitch`, which provide a way to alter the structure of the DOM based on data.

Q6: How do you use directives for event handling in AngularJS?

A6: Directives in AngularJS can handle events using event binding (`(event)="handler()"`) or by listening to native DOM events (`@HostListener`). This allows components to respond to user interactions like clicks, keystrokes, or mouse movements.

Q7: What is the difference between attribute and structural directives in AngularJS?

A7: Attribute directives in AngularJS modify the behavior or appearance of an element or component by manipulating its attributes or styles (`ngClass`, `ngStyle`), while structural directives (`ngIf`, `ngFor`, `ngSwitch`) alter the structure of the DOM by adding or removing elements based on conditions.

Q8: How do you use pipes in AngularJS?

A8: Pipes in AngularJS are used to transform data before displaying it in the view. They are added to binding expressions (interpolation, property binding) using the pipe (`|`) operator. AngularJS provides built-in pipes like `DatePipe`, `UpperCasePipe`, `LowerCasePipe`, and allows creating custom pipes for specific transformations.

Q9: What are pure and impure pipes in AngularJS?

A9: Pure pipes in AngularJS are stateless and only run when the input value changes, optimizing performance by preventing unnecessary recalculations. Impure pipes can have side effects and run on every change detection cycle, potentially affecting performance.

Q10: How do you create custom pipes in AngularJS?

A10: Custom pipes in AngularJS are created using the `Pipe` decorator or `@Pipe` decorator in TypeScript. They transform input data for display in the view, taking arguments to customize their behavior and chaining multiple pipes for complex transformations.

Q1: What is routing in AngularJS?

A1: Routing in AngularJS is a mechanism for navigating between views or pages in a single-page application (SPA). It maps URLs to different components and manages the application state based on the current route or location.

Q2: How do you set up routing in AngularJS?

A2: Routing in AngularJS is set up using the `RouterModule` and its associated components (`RouterModule.forRoot()` for root routes and `RouterModule.forChild()` for feature modules). Routes are defined with path patterns, component mappings, and optional route parameters or data.

Q3: What are AngularJS route guards?

A3: AngularJS route guards are used to protect routes from unauthorized access or perform additional actions before activating a route. Types of route guards include `CanActivate`, `CanDeactivate`, `Resolve`, and `CanLoad`.

Q4: How do you handle route parameters in AngularJS?

A4: Route parameters in AngularJS are accessed using the `ActivatedRoute` service (`snapshot.params` or `paramMap`) or by subscribing to parameter changes. They allow passing data between routed components based on dynamic URL segments.

Q5: How do you handle optional route parameters in AngularJS?

A5: Optional route parameters in AngularJS are defined in the route configuration with a colon (`:`) followed by the parameter name and a question mark (`?`). They are accessed similarly to regular route parameters but provide flexibility in routing based on user input.

Q6: What is lazy loading in AngularJS routing?

A6: Lazy loading in AngularJS routing involves loading modules or components asynchronously when needed, based on the current route. It improves initial page load times by splitting the application into smaller bundles that are loaded on demand.

Q7: How do you handle nested routes in AngularJS?

A7: Nested routes in AngularJS are defined within parent routes by specifying child routes in the route configuration. They allow organizing application views hierarchically, with parent components containing router outlets to render nested child components.

Q8: What is AngularJS routing with child routes?

A8: AngularJS routing with child routes involves defining routes within parent routes using the `children` property in the route configuration. It allows creating nested views and handling navigation between parent and child components based on route configurations.

Q9: How do you handle redirections in AngularJS routing?

A9: Redirections in AngularJS routing are handled using route guards or by defining a default route (`redirectTo`) for unmatched routes. They allow redirecting users to specific routes or components based on application logic or user actions.

Q10: How do you handle query parameters in AngularJS routing?
