1 - What are some key features of Angular 6?
Angular 6 introduced several new features such as the Angular Elements package, Angular Material Starter Components, and improved Angular CLI workspaces. It also included updates to RxJS, support for tree shakable providers, and the ability to configure budgets in the Angular CLI for better control over bundle sizes.
2) Can you explain what Angular Elements are?
Angular Elements is a new feature in Angular 6 that allows you to package Angular components as custom elements (web components). This makes it easier to use Angular components in non Angular applications and simplifies the process of integrating Angular components with other frameworks or vanilla JavaScript code.
3) How does Angular 6 improve performance?
Angular 6 introduced various performance improvements, such as reduced bundle sizes through tree shakable providers, optimized build processes with the Angular CLI, and updated RxJS to version 6 for better efficiency in handling asynchronous operations. These enhancements help improve the overall performance of Angular applications.
4) What is the significance of Angular Material Starter Components in Angular 6?
Angular Material Starter Components provide a set of pre built UI components based on the Material Design specifications, making it easier for developers to create consistent and visually appealing user interfaces in their Angular applications. With these starter components, developers can quickly add common UI elements without having to build them from scratch.
5) How does Angular 6 support progressive web applications (PWAs)?
Angular 6 includes built in support for service workers, enabling developers to create PWAs that can work offline, load faster, and provide a more engaging user experience. By generating service workers with the Angular CLI, developers can enhance their applications with features like caching, push notifications, and background sync, making them more reliable and responsive.
