1 - Angular version used: Angular 6, the latest stable version.
2) Difference between component and directive: Components are reusable UI blocks with their own HTML template, CSS style, and behavior. Directives modify the behavior of existing DOM elements.
3) Life cycle hooks: ngOnInit, ngOnChanges, ngDoCheck, ngAfterViewInit, ngAfterContentInit, ngOnDestroy
4) Data binding types: One way data binding ({}) for displaying data in the view, two way data binding [(ngModel)] for updating the data in both the view and the component.
5) Routing: Defines URL based navigation, allowing users to move between different pages of the application.
6) Services: Singleton objects that provide functionality and share data between components.
7) Dependency injection: Allows Angular to automatically inject dependencies (services, components) into components.
8) Observables: Represent asynchronous data streams that provide a sequence of values over time.
9) Angular Material: A library of UI components that provides a consistent and professional look and feel to Angular applications.
10) Reactive forms: Form management approach that uses observable data streams to control form values and validation.
11 - Component communication: Components can communicate through services, event emitters, or NgRx.
12) Unit testing: Angular provides a testing framework for writing unit tests for components, services, and directives.
13) TypeScript: Angular is built with TypeScript, a superset of JavaScript that adds type checking and other advanced features.
14) Performance optimization: Angular uses change detection to efficiently update the view when data changes.
15) Angular CLI: Command line interface that simplifies Angular development and provides scaffolding for new projects.
