Standalone Component in Angular :
_________________________________________
Angular's new standalone component feature allows for a more modular and tree-shakable approach to building applications. By marking a component as standalone, Angular knows that this component doesn't rely on being part of an NgModule and can be used independently.
This can be particularly useful for:
Simplifying the bootstrapping process.
Creating reusable components that can be easily shared across different parts of the application or even across different applications.
Improving the tree-shakability of the application, potentially reducing the final bundle size.

Non Standalone Component in Angular:
We can still able to create Non-standalone component in angular .The standalone component is optional . It provides you additional feature to your angular application . If you do not want to make your component is standalone , you need to ensure it is part of an NgModule .
eg:
Define the Component Without the Standalone Flag:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'your-app';
}
Include the Component in an NgModule:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Why You Might Choose Non-Standalone Components
Familiarity and Compatibility:
Most existing Angular applications are built using NgModules. If you are maintaining or building on top of an existing codebase, using NgModules might be more straightforward.
Dependency Management:
NgModules can manage dependencies and shared components/services, making it easier to structure larger applications.
Lazy Loading:
NgModules can help in configuring lazy-loaded routes, which can improve the initial load time of the application.
