What is the difference between ngFor and ng-container in Angular?

ngFor is a structural directive used to iterate over a collection, while ng-container is a grouping element that doesn't render in the DOM.

Can you give me an example of how to use ngFor?

Sure! You can use ngFor like this: <div *ngFor="let item of items">{{ item }}</div>.

And how would I use ng-container with ngFor?

You can use ng-container to group elements without adding extra nodes: <ng-container *ngFor="let item of items"><div>{{ item }}</div></ng-container>.

Are there any performance implications of using ng-container?

Using ng-container can improve performance by reducing the number of DOM elements, which can lead to faster rendering.
