Introduction: "standalone" components in Angular offer a simplified approach to building applications by reducing reliance on "NgModules" . This approach includes standalone components, directives, and pipes that streamline the authoring experience. It enables existing applications to gradually and optionally transition to this new style without introducing breaking changes. Example Standalone Component: Let's delve into a practical example of a standalone component: Explanation:     -  selector: Specifies the HTML selector for the component (ngbd-table-complete).     -  standalone: true: Marks this component as a standalone component, signaling its independence from NgModules .     -  imports: Lists the modules and components used within this standalone component (DecimalPipe, FormsModule, AsyncPipe, etc.).     -  templateUrl: Points to the external HTML template file for the component (./table-complete.html).     -  providers: Declares the servic

If template is provided, you should not also supply an external template file using the "templateUrl" property. Syntax: Purpose and Usage:     -  Purpose: Convenient for smaller components or when the template is simple and can be easily maintained within the component file.     -  Usage: Include the template property within the @Component decorator, providing the inline HTML   "template" . Example: Assume you have an Angular component named "ExampleComponent" and want to use an inline "template" for it. In this example, the "template" is directly embedded within the @Component decorator. The "{{ name }}" syntax is Angular's interpolation syntax, allowing dynamic content insertion. When to Use:     -  Use template when your component's template is relatively simpl
