1 - Explain Angular 5's Ivy compiler.
Ivy is a new compiler in Angular 5 that replaces the View Engine compiler. It improves performance, reduces bundle size, and enables better tree shaking.
2) How does Angular 5's Change Detection work?
Angular 5 uses a zone based Change Detection mechanism. When a property in the application changes, a zone is triggered which schedules a change detection cycle. During this cycle, Angular checks if any of the components have pending changes, and if so, it updates the DOM accordingly.
3) What are the key features of Angular 5's TypeScript support?
Angular 5 provides strong TypeScript support, including type checking, autocompletion, and refactoring. It also supports decorators, generics, and interfaces.
4) How can you improve the performance of an Angular 5 application?
There are several ways to improve the performance of an Angular 5 application, including using change detection best practices, optimizing component rendering, and avoiding unnecessary DOM manipulations.
5) What are the best practices for writing Angular 5 components?
Best practices for writing Angular 5 components include using lifecycle hooks, following the single responsibility principle, and keeping components small and focused.
6) How can you debug an Angular 5 application?
There are several ways to debug an Angular 5 application, including using the built in debugging tools, using third party tools, and logging errors and warnings.
7) What are the key differences between Angular 5 and previous versions of Angular?
Angular 5 introduces several new features and improvements, including the Ivy compiler, improved TypeScript support, and better change detection performance.
8) How can you use Angular 5 to create progressive web apps?
Angular 5 provides several features that can be used to create progressive web apps, including service workers, web push notifications, and offline caching.
9) What are the best practices for testing Angular 5 applications?
Best practices for testing Angular 5 applications include using unit tests, integration tests, and end to end tests.
10) How can you deploy an Angular 5 application to production?
There are several ways to deploy an Angular 5 application to production, including using the Angular CLI, Docker, and serverless platforms.
11 - What are the key trends and future directions for Angular development?
Key trends and future directions for Angular development include the continued evolution of the Ivy compiler, improved performance, and better support for mobile and serverless development.
12) How can you use Angular 5 to create reusable components and directives?
Angular 5 provides several features that can be used to create reusable components and directives, including ngModules, dependency injection, and content projection.
13) What are the best practices for organizing and structuring Angular 5 applications?
Best practices for organizing and structuring Angular 5 applications include using lazy loading, feature modules, and shared services.
14) How can you use Angular 5 to create complex forms and data validations?
Angular 5 provides several features that can be used to create complex forms and data validations, including reactive forms, validators, and form builders.
15) What are the key advantages and disadvantages of using Angular 5?
Key advantages of using Angular 5 include its strong TypeScript support, comprehensive tooling, and large community. Key disadvantages include its steep learning curve and potential for performance issues in some scenarios.
